A rather interesting example shows up in Elantris. Near the start there is a mention of Hrathen as the savior of Arelon which most simply put down to simply stating his thoughts. It isn't until the end that you find out that Hrathen defects when he realizes how evil Dilaf is, and then sacrifices his own life to kill him, saving the entire joint population of both Arelon and Teod from being annihilated by the Derethi cult.
Genesis 3:15 'he will crush your head, and you will strike his heel.' If you're Christian, this is foreshadowing to Jesus punishing Satan (the snake) ... a few thousand years before he was born.
As well as Isaiah, Jeremiah, and every other prophetic book. This is to be expected, considering the nature of what a prophecy is.
In addition, many Old Testament events are similar to events in the New Testament.
The Fellowship of the Ring has this ironic example: Frodo says, "So far, my only hope has been to get here [Rivendell]. I hope I shan't have to go any further. ... I have had a month of exile and adventure, and I find that has been as much as I want." Guess what the next two books are about?
Also in Fellowship, Elrond says to Boromir, "Slow should you be to wind that horn again until you stand once more on the borders of your land and dire need is upon you." The next time he uses the horn, just before his death, fits these circumstances perfectly.
Also in The Bishop's Heir, Dhugal is found to have very strong shields which no one can account for in his known heritage. Kelson's mental touch is unbearably painful, Morgan's less so, and Duncan's even less. This makes sense later when it's revealed the Duncan is Dhugal's father, which makes Morgan also a blood relative.
Early in The Quest for Saint Camber, Rothana asks Kelson to help encourage a love match between his squire (soon-to-be knight) Jatham Kilshane and the Princess Janniver. At the time, Kelson teases her about playing matchmaker, and she will do so again two years later for Kelson himself.
The morning after Duncan reveals himself as Deryni by showing his aura while bestowing Dhugal's accolade, Arilan gives him a severe reprimand for doing it without discussing it with him and Cardiel. At one point, he says, "It could be worse, I suppose. You could have done it at the altar, in full pontificals. Now, wouldn't that have been a coup?" A couple of years later, Duncan will do exactly that, consecrating a new altar by extending his aura over it, with an archbishop standing at each elbow, and again while elevating the Host and the Chalice in the celebration of the basilica's new Camber chapel's first Mass.
In the Chamber of Secrets film, after the scene in which McGonagall describes the Chamber of Secrets, which has been hidden for centuries, it fades to a shot showing exactly what the characters are searching for: the secret entrance to the chamber. It's not until the end of the film that they learn that's what it is.
Many of Professor Trelawney's predictions, while mostly inaccurate, sometimes end up echoing events later in the book. The most obvious example is in Half Blood Prince, in which Trelawney goes over Tarot readings. The Tower comes up, and Trelawney uses it to predict Harry's death... again. Later in the book, in a chapter titled The Lightning-Struck Tower Snape kills Dumbledore on top of the astronomy tower.
And of course, you have to consider also the fact that Harry did die in Deathly Hallows. Sort of. He was Only Mostly Dead.
Ron is king of this. He says about Tom Riddle "maybe he killed Myrtle, that'd have done everyone a favour." Riddle did kill her!
In Deathly Hallows, Ron almost predicts the taboo on saying "Voldemort." The exact words were "It feels like a jinx or something."!
A bunch of the Horcruxes are even shown in the book, such as Slytherin's locket and Ravenclaw's tiara, although this overlaps with Chekhov's Gun.
Harry and Ron foreshadow the events of the Tri-Wizard Tournament fairly early in Goblet of Fire, when making up catastrophes that would happen to them for their Divination homework.
An incredibly early bit of Foreshadowing occurs right in book one, when in an echo of his being Sorted, Harry dreams that a voice comes from Quirrell's turban telling him he should be in Slytherin. Apart from the fact we later find out he has qualities Slytherin (and Voldemort) prized and that he obtained some of these due to his link with Voldemort, there's the fact that of course Voldemort himself was under Quirrell's turban. Sometimes it seems as if Tonks's notion that Harry has Seer blood may not be that far off the mark...
This happens even in throw-away lines! In Harry Potter and the Chamber of Secrets after Harry was sent down the wrong chimney via Floo Powder, Draco is seen examining a cursed opal necklace that claimed the lives of 19 Muggles. Sound familiar? Not to mention that Draco had also shown interest in the Hand of Glory, which should also sound familiar for the very same reason.
And he (Harry) is standing in the very cabinet that Draco uses to smuggle the Death Eaters into Hogwarts in Half-Blood Prince. Also note that Harry never closes the door to the cabinet all the way, which would result in him getting transported away.
When Harry and Professor Dumbledore enter Slughorn's house in Half Blood Prince, they see a grandfather clock lying "splintered at their feet, its face cracked, its pendulum lying a little farther away like a dropped sword." This seems to foreshadow Dumbledore's death later in the book.
From the second book onward, Harry is mentioned to have abilities akin to Voldemort, particularly his ability to speak to snakes, showing that Harry contains a part of Voldemort's soul, making him the seventh Horcrux that Voldemort never actually intended to make.
In Dragon Bones, Oreg, who is a magically bound slave, whose life is connected to castle Hurog, and a ring which Ward inherited, tells Ward about the time when he annoyed his then master so much that the man had him whipped - by someone else. Oreg points out that, had his master himself beaten him, he would have run the risk of killing him (which would have been what Oreg had planned, his unlife was that miserable). Only the wearer of the magic ring can kill Oreg, otherwise he's immortal. Some time later, they all have become traveling adventurers, Ward finds a man with a painful stomach wound, and puts him to death, using a specific method that kills immediately and painlessly. He later kills Oreg, as this is the only way of preventing the eponymous dragon bones from falling into enemy hands. It turns out that Oreg had planned his Heroic Sacrifice for a long time before Ward realized he would have to do it.
Early in Wyrd Sisters, Granny Weatherwax says "You'd have to be a born fool to be a king." By the end of the book, the court Fool has become the king. And not only that, he is a 'born fool'—his father and grandfather were Fools before him.
A similar one was used later in Men at Arms. It's stated that you'd have to be a fool to try breaking into the Assassin's Guild. The perpetrator actually disguises himself as a fool to do just that.
Characters in previous City Watch books remark that there's no reason why the older but perfectly healthy Lady Sybil shouldn't be able to have children. It still takes her husband the whole length of The Fifth Elephant to get the happy hint.
In Thief of Time there's a weird little section where Lu-Tze cuts off a Yeti's head in order to show Lobsang their ability to manipulate time and avoid death. It seems sort of out of place, especially considering they're supposed to be in a bit of a hurry to get to the city, until Lu-Tze says "I hope I'm never that desperate," at which point you are absolutely, without-a-doubt certain that by the end of the book he will be. Of course, this may also just be an example of The Lawof Conservationof Detail and readers being Genre Savvy.
More cryptically, Death in the same novel is unable to see Lobsang Ludd. This appears to be hinting that Lobsang is immortal, until Fridge Logic reminds the reader that Death has seen plenty of other immortals before. The real reason turns out to be far stranger than that: Lobsang's life as an individual isn't destined to end with his death at all; instead, he ceases to exist as Lobsang when he merges with his other self, Jeremy Clockson.
It's funny because Polly had just received a pair of socks from an unknown benefactor to help her more convincingly pass as a boy. By the end of the book, it's revealed that every member of their squadron, even Sergeant Jackrum, is a woman in disguise. And Jackrum was the one who gave Polly the socks, which quickly caught on.
In Assassin's Quest by Robin Hobb, the character Kettle is part of a group who's looking for the White Prophet, and says with respect to their search "Perhaps it is a fool's errand that I go on." The White Prophet turns out to be the Fool.
In Black Legion, Djedhor is more responsive of the two Rubrics and Khayon hopes that he has retained more of his humanity. In the end, however, it's subverted, as it's the less responsive Rubric, Mekhari, that regains his sentience and sacrifices himself to save Khayon.
Happens throughout the second part of Foundation and Empire, this part of the book being full of situations that not only hint the powers of The Mule but also wouldn't have been possible without them; the casual reader passes by without noticing anything out of place, is only when you have completed the book and start rereading it that everything makes sense.
Two notable examples occur in John Steinbeck's Of Mice and Men. In the very first scene, George complains about how Gentle Giant Lennie always accidentally kills his pet mice. About halfway through the book, Carlson shoots Candy's dog. Both of these nicely build up the drama of the last chapter.
The whole book is dripping with foreshadowing if you know where to look.
An excellent example of foreshadowing is The Wheel of Time in The Great Hunt Turak mentions that the Emperess of the Seanchan Empire rules from the Court of the Nine Moons, and her favorite daughter is named Tuon. In The Shadow Rising Mat Cauthon is told he will marry the Daughter of the Nine Moons. Guess who the Daughter of the Nine Moons is? To put this in perspective The Great Hunt is the second book in the series, The Shadow Rising is book 4, and The Winter's Heart where Tuon actually enters the story is book 9.
This is in fact pretty much the entire principle behind the Wheel of Time books. That and clothes.
Early in the book, when Jane is ill, Darcy and Elizabeth discuss the eventuality of Mr. Bingley suddenly leaving Netherfield at a friend's request. Darcy thinks it would be a lack of character to yield so easily to a friend, and Elizabeth thinks it's perfectly natural to be influenced by those who are dear to you. Guess who changed their opinion when Bingley does leave Netherfield in a hurry at his friend's request?
About halfway through, Elizabeth says to Darcy, "I had not known you a month before I felt that you were the last man in the world whom I could ever be prevailed on to marry." He is.
In the first Redwall book, Cluny had a nightmare where he was being chased by Martin the Warrior, and as the sword "struck" him, he was woken up by a giant bell. His final battle is in the bell-tower, where Matthias uses Martin's sword to chop the rope keeping the bell up, and it lands on Cluny's head.
One example, right from the start: Lord Eddard Stark, on his way back from an execution, finds a direwolf (the symbol of his house) killed after being run through with the horn of a great stag (the symbol of House Baratheon). Sure enough, the coming of his old friend Robert Baratheon leads to the crippling of his son, the outbreak of civil war in Westeros, and his execution. It's also an example of in character foreshadowing: everyone else gets really uncomfortable when they see it, and his wife Catelyn wishes he would put more stock in its meaning.
Beyond the Wall, Jon Snow is told a tale about his ancestors that involved two people hiding the crypts of Winterfell so well that no one found them. Guess how Bran, Rickon, and their group survive the Greyjoy-Bolton attack of Winterfell.
Animorphs is full of this, usually in the form of remarks the characters make. Read the series. Then read it again. You will be amazed. Here are only a select few examples from only the first book:
Marco: "We'd be totally famous. We'd get to be on Letterman for sure." At the end of the series, they're practically the most famous people on Earth. Marco not only gets on Letterman, he even gets his own show.
Visser Three: "[...] And then I'll be Visser One." He does get promoted to Visser One near the end of the series.
Jake (as narrator): "I think maybe the Andalite meant even more to Tobias than to the rest of us." Elfangor, the Andalite in question, is later revealed to be Tobias' father.
Marco: "Maybe it's your own brother you'll end up destroying." Jake: "Yes, maybe that's what will happen." Jake ends up ordering his cousin to kill his brother.
Jake: "Tobias! Get a grip. Don't start eating mice just because you're in a hawk's body. What's next? Roadkill?" Tobias ends up eating mice exactly because he gets stuck in a hawk body. He also resorts to roadkill when he has bad hunting luck.
Cassie: "What are we going to do with dolphin morphs?" They acquire dolphin morphs shortly after, and use them on quite a number of underwater missions.
Jake (at Tobias): "Too late for you to morph back now." Uttered in reference to the strategic situation, right before Tobias passes the time limit and gets stuck in his hawk body.
Also done without words in the first book. Tobias is the one who has the deepest connection with Elfangor, who stays with him the longest. He does not know why, but we find out why in The Andalite Chronicles, with the parental reveal.
The Ellimist Chronicles begins and ends with the Ellimist visiting a dying Animorph. He admits that he did not cause him/her to be an Animorph, and that it was random chance. According to Megamorphs 4, this means that this can only be Jake or Rachel. It turns out to be Rachel.
Most of the information about Z-Space's finer workings comes from the books narrated by Marco. Marco's Dad is the first human to discover the existence of Z-Space and build a transmitter.
Done rather badly in Twilight: Bella says something like "nobody's gonna bite me" in the first chapter. If you already know that the book is about vampires, which the back cover explicitly mentions, then this is pretty blatantly obvious.
That could just be dramatic irony.
The Horus Heresy books, particularly early on, seem to be a contest between the authors as to who can foreshadow the Foregone Conclusion best. There are a lot of comments about how space marines fighting other space marines would be unthinkable, gods and religions, particularly malignant ones, are a silly idea, etc etc.
In Angel Exterminatus, Forrix comments that he's always hated a model Warhound Titan Perturabo owned. In Storm of Iron, set ten millennia later, he gets into a fight with one and comes off second best.
In the Inheritance Cycle, Eragon at one point asks Brom what his mother was like. Brom describes her as proud and dignified, which led to her downfall, but also willing to help others. Fridge Logic kicks in when you realize that Brom was an outsider to Carvahall who shouldn't have known this. When we are told that Morzan was Eragon's father, that makes even less sense; why would Brom say that about Morzan's consort? How could he have known she had a nicer side. In the third book, we get an answer: he and Selena had fallen in love and produced Eragon.
In Z for Zachariah, a character tells the protagonist "Ann Burden, you're going to wish I'd never come here." At the time he doesn't seem serious, but turns out to be very right.
Matthew Reilly's Hover Car Racer has several bits of foreshadowing for important races. In professional races, the steering wheel is the only part of the car required to cross the line to finish the race if the car crashes close to the line (except for a particular race, and this becomes important too). Jason has dreams about blacking out on Liberty's Elbow (a tight hairpin turn around the Statue of Liberty). The Bradbury Principle is mentioned a couple of times before it happens.
In Dale Brown's Fatal Terrain, Brad Elliott says that he "always thought I'd buy the farm in the cockpit of a B-52 after just saving the world from thermonuclear meltdown". Guess what...
The lovely thing about the Haruhi Suzumiya novels is the anachronistic order which it's presented. There are foreshadows almost everywhere. For example, in Snow Mountain Syndrome, Kyon casually mentions a crazy ex-classmate who wanted to confess to Nagato. In the next novel, there's a story about it. The best foreshadow was from the first book, Melancholy, where Kunikuda mentioned that Kyon liked strange girls, and Kyon protests, claiming that she was just a good friend, and nothing more. In the ninth novel, Sasaki is introduced, and she IS strange enough to have her own anti-SOS Brigade.
A truly hilarious example in the first novel. When Haruhi decides to recruit (kidnap) Mikuru into the (then unnamed) SOS Brigade, as Haruhi runs off to retrieve her, Kyon jokingly wonders if Haruhi had finally found an alien. Having run into Haruhi as she was leaving the club room, the next paragraph (only a sentence long), describes him entering the room. The very next line after that is, "Yuki Nagato was already in the club room." (From the English translation)
Bokonon tells the protagonist of Kurt Vonnegut's Cat's Cradle what he would do if he were "a younger man"...such as the protagonist. It is heavily implied that John does exactly what Bokonon says. We know for a fact that he does part of it by the end of the book.
Percy Jackson and the Olympians: In The Last Olympian, when Percy is trying to determine the most strategic location for his one mortal point, he chooses the small of his back in favor of an armpit, being more dignified. Anyone want to guess where Luke's body's Achilles spot is?
The novel To Kill a Mockingbird spends an entire chapter detailing local racist Bob Ewell's attempts at getting revenge on everyone he blames for being outed as a liar (he had beaten his daughter after catching her trying to seduce a black man and forced her to accuse the innocent man of rape. Despite evidence of his innocence, the man was convicted and fatally shot trying to escape.), stalking the man's widow, the trial judge, and explicitly threatening the man's lawyer, Atticus Finch. In the next chapter, as Atticus' children prepare to go to a Halloween party, their aunt mentions an uneasy feeling, "Something just walked over my grave". The children are viciously attacked by Ewell on their way home, and it is all but stated that they would have been killed had someone not heard their screams and come to help.
When Atticus, who has made it clear that he is adverse to violence, goes out into the neighborhood to "take care of" the rabid dog it foreshadows both his battle against the legal system and the climax of the book.
And Then There Were None. Soon after arriving to a manor with several others, one of the characters goes into his room and takes a bath while pondering what he's going to do next: "Warm steaming water - tired limbs - presently a shave - a cocktail dinner. And after - ?" He dies during the dinner.
In Myth-Chief, Aahz and Skeeve are competing over who gets to be the new president of M.Y.T.H., Inc. Early on, Nunzio accidentally calls Bunny "boss", foreshadowing who eventually gets the job.
In Moby-Dick, the landlord of the inn at the beginning of the book is named Peter Coffin. At the end, Ishmael survives by clinging to a coffin.
The 2003 BIONICLE book Tales of the Masks is full of foreshadowing, hinting at a mysterious, forgotten past and an ancient city called Metru Nui. The following two years focused entirely on this. Later, in the '05 book Time Trap, Toa Vakama received a vision that faintly hinted at the '06 storyline.
Earlier than that, the Bahrag queens in the 2002 book Beware the Bohrok compare their minions, the titular Bohrok to the Toa heroes, calling them their brothers. Some years later, it's revealed that the Bohrok and the Barhag weren't evil at all, they had only been serving the will of Physical God Mata Nui, the same as the Toa. Later still, we learn that the Bohrok were once Matoran, the same "species" that the Toa belong to.
A very coy example appears in Steven Brust's Phoenix, in which Vlad asks Loiosh if Rocza is pregnant in passing. This seems innocuous at the time, except that Loiosh replies that Rocza isn't pregnant, but is "a little closer to Cawti". Turns out that Vlad should have been asking Cawti whether she was pregnant.
In the Sword of Truth novels, the best example is in the sixth book, Faith of the Fallen. Right after Nicci forcibly takes Richard prisoner and right before he leaves with her to the Old World, Kahlan tells Richard that he should, "Carve something to make Nicci see that you should be free." Richard dismisses this as unnecessary and silly. At the climax, when Nicci sees the statues on the cover of the book that Richard carved, she has an epiphany, sets Richard and Kahlan free, and pulls a Heel–Face Turn.
In the first chapter of Dead Souls the author mentions that Chichikov (the protagonist) is able to talk about custom officials "as if he had been one of them". Much later we'll learn that this has indeed been the case - and that he tried a big smuggle operation, which almost would've made him a rich man.
Originally, each Magic School Bus book ended with Ms. Fizzle setting up classroom decorations and donning an outfit relating to the subject of the next book. (eg, the book preceding the class' trip inside a hurricane ended with her displaying weather-measuring equipment and wearing a dress boasting stormy imagery.) Series Fauxnales had Ms. Frizzle wear a dress covered in question marks on the last page.
In Conspiracies, Repairman Jack encounters the Twins, agents of the Ally who are the basis for that Verse's "men in black" rumors, and are noted for driving around with their headlights off. After his attempt to get away from the pair causes their deaths, Jack vacates the area, driving away in the dark with his headlights off. Guess whose job he just inherited?
In Dostoevsky's The Idiot, Nastassya Filippovna makes a comment about Rogozhin becoming consumed by his passions and ending up being exiled to Siberia. Much later on, Rogozhin murders her...and is sentenced to fifteen years' hard labour in Siberia.
Early in S.E. Hinton's That Was Then, This Is Now, Byron muses about how Angela would look beautiful even with all her hair cut off. Later in the book, his friend Mark does exactly that to her while she's passed out drunk.
Jack London's short story, "To Build A Fire", is most frequently used to teach this trope in high school English classes. The reader knows the main character's a goner long before he does.
In The Kite Runner, Amir reads Hassan a story about Rostam and Sohrab. Rostam kills Sohrab in battle, not knowing that Sohrab is his son. Later in the book, Amir blames himself for Hassan's death, and learns that he was his half-brother.
In "Lost In a Good Book", second of Jasper Fforde's "Thursday Next" series, pairs of amusingly named agents appear throughout the novel. Examples include agents 'Kannon' and 'Phodder', and 'Lamm' and 'Slaughter'. These names foreshadow their inevitable horrible deaths.
Among the various examples in Cerberon is this gem: When George and Cerberon are discussing what to do with the bodies of two highwaymen they had just killed, Cerberon asks, "Shouldn't we bury them?" to which George replies, "No. Leave them for the carrion birds. Maybe they can carry their wretched souls up to Heaven." Later on, they meet a family of skraad, human-sized intelligent avian carrion birdswho can lead lost spirits on to their afterlife. In an interesting Call-Back to George's foreshadowing statement, one of the skraad tells another character, "There is nothing in the sky for the soul. It returns to the Source and the body nourishes more life."
Multiple books foreshadow the death of Harry Dresden. Prominent examples include, Quintus Cassius's death curse: "DIE ALONE!", and the tombstone Harry was given as a threat by Bianca. Its epitaph: He died doing the right thing. It's not wrong.
In Dead Beat, when Harry is being tortured by Cassius, he uncharacteristically convinces himself that he'll be saved by divine intervention, hoping for the appearance of one of the Knights of the Cross. Instead, he's saved by Waldo Butters one of the least likely heroes imaginable. Eight books later, at the end of Skin Game, Butters takes up the sword Fidelacchius to become one of the Knights.
In Summer Knight, diminutive, nervous changeling Fix wales the tar out of Lloyd Slate, who would be well out of his weight class even were he not the powerful Winter Knight, with a wrench. By the end of the book, Fix becomes the new Summer Knight, designated opponent to the Winter Knight.
Early in Aunt Dimity Goes West, Bill marshals many arguments to convince Lori to vacation in Colorado with the boys and Annelise; among them, he cites the many wonderful activities available to the boys and says, "They'll have a tale or two to tell their friends when they start school in the fall, that's for sure." Yes, and some of those tales will prove more exciting than even he bargained for—so exciting that they prompt the school's headmistress to summon Bill and Lori for a conference early in Aunt Dimity Vampire Hunter.
Jack McDevitt really likes to do this before killing off any vaguely important characters. When he starts talking about how one character will think back to this moment, later, it's often because it's the last time they'll see another character alive. He's deliberately not very subtle about it.
In Dorothy L Sayer's Busman's Honeymoon, Peter and Harriet arrive at their honeymoon cottage and send Bunter to knock loudly when nobody lets them in, saying 'Wake Duncan with thy knocking'. This is what Macbeth says when Duncan is dead (Wake Duncan ... I woulds't thou coulds't). The person being knocked for is dead.
Catching Fire contains two. Katniss has a dream that essentially depicts the epilogue and the resolution of the love triangle is foreshadowed when the characters describe the wedding ritual of District 12 which includes the couple starting a fire and toasting a piece of bread. Take one guess as to whether the girl on fire ends up with the boy with the bread or with the other guy.
In The Hunger Games, she first notices Rue in training while practicing with spears. In the Games, Rue is killed by a spear.
The first time Gale appears he's holding a piece of bread pierced by an arrow. Foreshadowing that Katniss will choose the boy with the bread. Tough luck to foreshadow that you'll be the Romantic Runner-Up.
In The Hunger Games, Peeta explains to Katniss that he wants to die as himself and not to be turned as a monster, and to show to the Capitol that he does not belong to them. It is cruelly ironic when you know that in Mockingjay, he is submitted to painful torture and brainwashing which turns him into a "mutt" eager for killing Katniss.
Professor Mmaa's Lecture: In a one-off gag, the termite student Nonobody wonders what are the chances that an auspicious miracle, such as an earthquake or another cataclysm, would happen before the professor asks him for his homework. Guess what happens near the end...
In the last book of Artemis Fowl, when watching Gobdaw's soul move on to the afterlife in bliss, Artemis wonders when that happens to them, if they would react the same.
In City of Bones, Simon makes a joke about Jewish Vampires. That's exactly what he ends up becoming in City of Ashes.
Witchlight stones will only illuminate in the hands of those who have angelic blood, and are thus typically only used by Shadowhunters. However, when Alec drops his, Magnus picks it up and it proceeds to glow, albeit in changing colors rather than pure white. Magnus's father, Asmodeus, is not one of the demons spawned by Lilith, he is a Fallen Angel, one of the ones that originally rebelled against God.
In Temple Trouble Verkan Vall is rattling off a bunch of information for a couple pages. Buried in there is the source of the story's problems, the name of the syndicate.
Near the beginning of the first Tales of the Otori book, Across the Nightingale Floor, Kaede complains about how little of use she's been taught: "I learned embroidery, but you can't kill anyone with a needle." Much later, she kills one of the main villains, with a needle.
In The Great Gatsby, a man that Nick dubbed "Owl-Eyes" wrecks his car. Guessed what happened with another character involving a car?
Tom Buchanan was involved in a car incident previously ... with a chambermaid in the passenger seat, revealing his infidelity. Another similar car incident later on in the book revealed adultery.
In Destined to Lead, Resurge mentions that a 'game' wouldn't be so fun if someone breaks an arm. Later on, guess who ends up breaking a few ribs? In book one, Kajiya encounters a spiede, in book two- she gets captured by them! (Even more subtle, the first cave had jagged walls as opposed to the second's smooth ones, signifying it was unused by spiedes, the first speide was there as a messenger for the Big Bads!)
Lucy Pavlov of Blonde Bombshell decides that her amnesia of everything past five years ago is either the work of her enemy or something she had done to herself, with good reason. Turns out it's because she's not actually human, but a bomb.
In The Fault in Our Stars, when Hazel, Gus, and Hazel's mom are on the plane, it's mentioned that Hazel and Gus pushed the play button on their movie simultaneously, but Gus's movie started before's Hazel did. This foreshadows that Gus dies later in the book: just like his movie starts first, his movie, i.e. his life, ends first.
In The Osmerian Conflict Marina's true identify is foreshadowed through a series of events. Firstly she never interacts with any Silician. Secondly she is found alone twice speaking to herself in a language not Terran. The third bit take a bit of a Genius Bonus in that a medic administers a test and says her tissue is highly dense and lacks any form of Silicon.
Early on in The Giver, we learn that Jonas' younger sister Lily has a stuffed toy elephant as her "comfort object", and that she believes that elephants are imaginary creatures that never existed (when he was little, Jonas had a bear, which was also supposedly imaginary). Much later in the book, Jonas receives a memory of an elephant being killed for its ivory by poachers. This is a major step in Jonas learning about the lost memory of sorrow, and it makes him realize just how much of the old world people have left behind.
In the Tairen Soul's first book, Lillis remarks that Ellie (her older sister) '[kisses] pain away better than anyone'. This comes several chapters before The Reveal that Ellie has a latent talent for healing magic, which the Fey theorize she has been using subconsciously all her life.
In A Bad Day For Voodoo, after Adam gets a voodoo doll made of Tyler to ensure that he won't tell the cops about the voodoo doll of Adam got made of Mr. Click, Tyler asks him how he paid for another one when they cost 80 dollars, since Adam was out of money. Adam doesn't answer. As it turns out, Esmeralda the doll-maker made the doll for free because Adam is The Chosen One.
The Vagina Ass Of Lucifer Niggerbastard shows an example of this, when the Priest Of The Dildo Staff, after looking into the future, informs the Fellowship that they will go up against the Latin League. They do.
King Dicksalsa actually foretells this first.
Also to note: Juno mentions having had sex with Turnus, Pallas & Camilla, before they were introduced.
In Brightly Burning, Kalira is wounded by an arrow, and seeing her injury motivates Lavan to become a better pyrokinetic. In the finale, she is killed by a crossbow bolt, and Lavan's resulting anger burns a forest down.
MARZENA: In Book One, on the first meeting between Lauren and Marian, Lauren has some weird feeling of déja-vu, a weird itch, like she's already seen Marian in a magazine or something, but she can't recall what exactly. Sure enough, we later learn that Lauren is really an Anti-Manchurian Agent briefed for a mission where she would need to get close to Marian, so that her Traumatized brain could absorb Marian's personality therefore cloning the Alpha Bitch's brain.
Midnight's Children takes this Up to Eleven, possibly even to the point of parody. The Framing Device is a narrator writing his autobiography, but he acts like a literature student performing a deep reading of a work, and excitedly references future events whenever he notices something significant. May even overlap with Doomed by Canon, as the narrator will sometimes spoil future events outright (particularly the deaths of certain characters).
As early as the first novel, Arthéon considered the possibility of the Soulless forming their own faction. It ended up actually happening a little before the fourth novel rolled in.
The third novel had a potion that disguised the Noob guild into Coalition players by changing the cursors, which are color-coded depending on in-game factions, from the Epire yelllow to the Coalition red. Gaea's cursor turned red for real between the third and fourth novel.
In the second novel, it's repeated several times that Sin, at the time assumed to be some kind of ancient artifact (he's actually a Source, basically a god), is supposed to be stronger than Lys and Ark'hen (Olydri's founding Sources) taken to together. Not only are the two basically his parents, but the fourth novel reveals that Dortös (another Source that live in Olydri) pitched in for his "conception" also.
