The Heroes of Olympus series. Hera/Juno does it while speaking with Jason about his destiny in the last chapter of The Lost Hero.
To Kill a Mockingbird: Heard in a tale Atticus relates over dinner. If it weren't for the use of the Title Drop, his tale would seem unimportant at the time, but it turns out to be a metaphor for one of the major themes.
The last five words of the novel The Silence of the Lambs are "the silence of the lambs," in reference to an intense conversation Clarice had earlier on with Lecter about witnessing lambs being slaughtered as a child.
Every version of Stephen King's The Dead Zone has featured the phrase "the dead zone." However, oddly enough each version ascribes the phrase a different meaning. In the original novel it referred to parts of Johnny's brain which had died during his coma, which became important when he had a crucial vision of the future — some elements of which he couldn't make out because they were in "the dead zone."
The Pendragon Adventure gets a lot of usage out of this trope, with the title usually relating to the turning point of the territory that has to be saved. It begins in the very first book, The Merchant of Death. Eccentric tradesman Figgis reveals himself to be selling tak, a deadly explosive. The Milago people are constructing it into a bomb as part of La Résistance. Cue Title Drop.
In Brave New World, John the Savage replies to Bernard's invitation for him to come and live in the "civilized" world by quoting Miranda's words from the final scene of Shakespeare's Tempest, pausing when he comes to the Title Drop.
He later recites the same words (and Title Drop) as an Ironic Echo, after his disillusionment with the values of said "civilized" world.
The Sholan Alliance: Lisanne Norman has managed to write the title of each book into the character dialogue or the character's thoughts.
It is usually done word for word, but on at least one occasion, paraphrased.
Till We Have Faces, by C.S. Lewis, waits until the final chapter to mention the title, making its meaning clear by context.
The book's Working Title was actually "Bareface" (the main character goes veiled through most of the book). His editor objected that people would think the book was a western. (Lewis observed that he didn't think that would hurt sales.) So the title was pulled from that line in the last chapter.
Also by C.S. Lewis, That Hideous Strength has this: "No power that is merely earthly," he continued at last, "will serve against the Hideous Strength."
A Song of Ice and Fire, both with the series name and the individual books A Game of Thrones, A Feast for Crows and A Dance with Dragons. In the second book, Daenerys sees a vision of her dead brother Rhaegar in the House of the Undying, in which he says of his baby son Aegon "He is the Prince Who Was Promised, and his song is the song of ice and fire". Dany later discusses it with Ser Jorah, but they can't figure out what it means.
While the title has been briefly mentioned, as of book 4 it is still not known what it actually is, though a popular theory has been pieced together from context and evidence. Rhaegar Targaryen believed that "the song of ice and fire" was something to do with the Prince Who Was Promised. At first, he thought that the Prince was his son Aegon, but later concluded that he'd been mistaken. This is what led him to seduce Lyanna Stark (Targaryen = fire, Stark = ice), presumably in the hope of fathering a Stark/Targaryen child who would be the Prince Who Was Promised. Since the role of the Prince Who Was Promised is to fight the Others, the title song is the cyclical/prophetic saga of a hero battling against the Others to save mankind. Important detail about the Rhaegar and Lyanna theory: a lot of fans are convinced that not only did Rhaegar and Lyanna have a child together but that that child was Jon Snow.
The Title Drop for A Game of Thrones most famously occurs in one of Ned's chapters in which he confronts Cersei, and is the first Title Drop in the live action adaption. Cersei famously counters with the phrase, "In the game of thrones, you win or you die." The phrase "game of thrones" is used several times afterwards throughout the rest of the series. The first Title Drop is by Ser Jorah, of all people, in response to Dany's claim that the common people are praying for Viserys's return to the throne. Interestingly, while all other Title Drops in the thousands-of-pages-long series indicates the importance of the situation, the very first one belittles the entire thing.
"The common people pray for rain, healthy children, and a summer that never ends," Ser Jorah told her. "It is no matter to them if the high lords play their game of thrones, so long as they are left in peace." He gave a shrug. "They never are."
In A Feast for Crows the Title Drop occurs in Asha's first chapter, although it's not a literal one: "We had one king, then five. Now all I see are crows, squabbling over the corpse of Westeros."
In A Dance with Dragons one character says, "Not all men were meant to dance with dragons" about Quentyn Martell after his death.
The Avi book "Sometimes I Think I Hear My Name" uses itself as the last line spoken.
House of Leaves is the title of a book Navidson brings with him on a journey into the labyrinth. It also occurs in one of the supplementary appendices which are connected with the main narrative, as part of a poem.
Title Drops occur in many, if not all Discworld books. The Colour of Magic, The Light Fantastic, Thief of Time and Thud! is even of the sort that the true title reference is explained later as having been different from the assumed reference, due to the cover (at least on the American printings).
In The Last Olympian, the final book in the Percy Jackson series, the goddess Hestia tells Percy that as the guardian of the hearth, she is the last olympian.
Robert Jordan's The Wheel of Time series takes each of its titles from the text of the book, usually from dialog between characters but occasionally from description; there is also quite often an excerpt from the Prophecies of the Dragon at the beginning or end of the book that does a Title Drop. The individual chapters within the books follow the same trend, though more loosely, often referring to an event or location which is not described in the exact phrasing as the chapter title. The ninth book, Winter's Heart, is in many ways a crux to the entire series, and this is foreshadowed in that the title phrase appears somewhere in almost every book in the series.
The last two words of every Sharpe book except the last two are the title, which often requires some slightly clumsy prose.
Happens in every single book of the Sword of Truth series, except for Soul of the Fire (a title which, incidentally, can't really refer to anything in the book. There is a fire spirit, but it's explicitly described as not having a soul). It gets slightly varied, as the Blood of the Fold of the third book were first mentioned in the second, and the last title, Confessor, as it's the title of one of the main characters, had been in common usage in the books since the first one.
A Scanner Darkly has this line: "Does a passive infrared scanner...see into me-into us-clearly or darkly?"
A great one happens in the short novel/novella They Shoot Horses Dont They, where the title is used in the last chapter as an explanation for why the main character shot his depressed girlfriend who couldn't kill herself—he had to put her out of her misery. (Don't worry, not a spoiler, it's the first thing in the book.)
The Crying of Lot 49 plays with this. The title is the final line of text, and deliberately makes absolutely no sense until then. It turns out that the 49th lot (property) at an auction is maybe relevant to the mystery, and Oedipa is waiting for that lot to be cried (sold). The book ends just before the crying starts, because Thomas Pynchon likes doing that sort of thing, so we never find out what happens.
Iain M. Banks does this at times in his Culture series, probably most notably in Use of Weapons, and also in Look to Windward and Matter.
Jennifer Government (though you can see it coming from the beginning of the chapter, lessening the impact).
I Am the Cheese: The Title Drop is the first person narrator's comment on the last line ("The cheese stands alone") of the Ironic Nursery Tune he has been humming to himself throughout the novel.
From the moment King Solomon starts referring to the Hand of Mercy, it's clear that Helen and Clem aren't just reassembling some old angel bones.
Tom Clancy usually puts the title of his novels into the text, usually at a critical point in the story or at the climax.
The people come with nets to fish for potatoes in the river, and the guards hold them back; they come in rattling cars to get the dumped oranges, but the kerosene is sprayed. And they stand still and watch the potatoes float by, listen to the screaming pigs being killed in a ditch and covered with quicklime, watch the mountains of oranges slop down to a putrefying ooze; and in the eyes of the people there is the failure; and in the eyes of the hungry there is a growing wrath. In the souls of the people the grapes of wrath are filling and growing heavy, growing heavy for the vintage.
The Color Purple does it towards the end of the book. It is somewhere in the middle of a long list of small things to be grateful for and enjoy. This philosophical/religious discussion would be unremarkable without the Title Drop.
Lilies of the Field has the protagonist quote scripture to try to get the stingy, English-deficient mother superior to pay him for his work.
Near the end of The Lord of the Rings Frodo reveals that he's written The Fall of the Lord of the Rings and the Return of the King.
When Frodo also first sees his friends after waking up in Rivendell, Pippin cheers for him and calls him "Frodo, Lord of the Ring!" Gandalf promptly scolds him.
The Sherlock Holmes novel A Study in Scarlet. "I might not have gone but for you, and so have missed the finest study I ever came across: a study in scarlet, eh?"
In the companion book to the Uglies series, Bogus to Bubbly, which explained many things that were left out of the series, Word of God states that the last word of each book was the name of the next book. Scott Westerfeld says that the first two were unintentional, though.
The first two? There are only three books in the series, so the last words of the first two would be the only relevant ones. Unless you're including Extras...
More specifically, the last word of "Uglies" is "pretty", the last word of "Pretties" is "special", and the last word of "Specials" is "ugly". Considering Tally's Character Development, these could be considered Arc Words.
The last word of "Extras" is "cake." Make of that what you will.
The Killer Angels drops its title in response to the "What a piece of work is man...," quote from Hamlet.
A rather clever example in the original novel A Clockwork Orange; it's the title of one of Frank Alexander's manuscripts, and Alex, upon seeing it, remarks on what a stupid title it is. Later, after being "rehabilitated", he suddenly blurts it out.
Stephenie Meyer's Twilight books do this in every single book, making the whole series' titles into an Anvilicious metaphor for Bella's life: ie, when she meets Edward, her life descends into twilight; when he leaves her, her world becomes dark in New Moon; The Volturi/fear eclipse everything else in Eclipse; and Breaking Dawn is when everything is working out all right. In the Swedish editions the Title Drops are inevitable, since the Swedish title of every book in the series is a quote from said book. The Short Life of Bree Tanner is the only exception; it was translated without any changes.
The Title Drop in Eclipse is more blatant. Bella calls Jacob her personal sun, balancing out the clouds of her depression, but says that she's choosing Edward. Jacob replies that he can handle the clouds, but that he can't fight an Eclipse.
"These were The Lovely Bones that had grown around my absense: the connections-sometimes tenuous, sometimes made at great cost, but often magnificent-that happened after I was gone."
The Title Drop in The Name of the Rose is intentionally opaque, showing up only in an untranslated Latin epitaph in the last line in the novel: Stat rosa pristina nomine, nomina nuda tenemus. This translates roughly to "the ancient rose continues to exist through its name, yet its name is all that remains to us," a line that touches on several of the book's themes.
Umberto Eco went on to say that, as a semiologist (a specialist in metaphors and symbols) he'd found that the Rose was the most used of symbols, to the point that it could be used as a symbol of almost *anything*. Meaning that it has become too charged with subtitles to actually mean anything any more. He deliberately chose the title to be the most portentous ever, but to not portent anything in particular. It is a semiotic joke, mister Moreau.
Number the Stars has its Title Drop during the fake funeral: Peter reads from Psalm 147, which describes God as "He Who numbers the stars one by one." The protagonist Annemarie looks out the window as he says this, wondering how this is possible considering how many stars she could see.
The title question in Agatha Christie's Why Didn't They Ask Evans? is the last thing spoken by the murder victim. The significant Title Drop doesn't come until near the end, however, when the heroine finds herself asking the very same question.
The Quantum Gravity series has three. The first two, Keeping It Real and Selling Out, come in the second book, in talking about what it means to be a demon: Keeping it real and never selling out. The Title Drop for the series as a whole finally makes sense of the series title.
The ghost glow was gone, but she had been Jone's ship and real enough before her capture by the Fleet's massive quantum gravity, so she hadn't fallen apart yet[.]
In the first of Jack L. Chalker's Quintara Marathon trilogy, The Demons at the Rainbow Bridge, one character says: "Three highly trained teams are about to set out on a racecourse blindfolded, where they will attempt to murder one another in their quest to catch creatures that will certainly eat the winners! Yes, indeed, beings of all races! Don't dare miss—The Quintara Marathon!" To which the character's telepathic parasite responds with Shut up, Jimmy! All the individual books also include a Title Drop.
"As one of the survivors of the lone southern strongpoint would say later, the defense of Isabelle had been hell in a very small place "
Anthony Horowitz's Diamond Brothers books all have incredibly lame puns as their titles, and each one gets Title Dropped, from "I Know Who You Killed Last Wednesday" to "South by Southeast".
My Sister's Keeper. While the title initially seems to refer to Anna's role as (involuntary) organ donour to her sister Kate, the actual Title Drop is done by Jesse, responding to a question about Anna's whereabouts with "Am I my sister's keeper?"
My Swordhand Is Singing contains two Title Drops. The first: "No, Milosh. I am not hurt," he said. "I am dying. But my swordhand is singing. I will take the sword into the village, and put an end to it." And the second: "Yes, Father. My swordhand is singing.
Besides, there is a point when the unfortunate and the infamous are associated and confused in a word, a mortal word, les misérables; whose fault is it? And then, when the fall is furthest, is that not when charity should be greatest?
In an interesting twist, Ted Dekker names the titles of the first three books of The Circle Series in the form of the last names of three serial killers in some later books. Showdown has Marsuvees Black, Skin has Sterling Red, and House has Barsidious White.
The Lord Peter Wimsey short story "The Article in Question" does it twice in ca ten pages, combining Title Drop with Chekhov's Boomerang. The title is dropped for the first time already in the preamble, where "the article in question" refers to a diamond necklace. The story proper deals with two french jewel thieves. The article in question turns out to be the french definite article, which has different form for male and female. One of the thieves, while impersonating a maid, slips up and uses the male form about himself, which leads to lord Peter solving the case.
A Deepness in the Sky: "I have students who are sure most of the stars are just like our sun, only much much younger, and many with worlds just like ours. You want a deepness that endures, a deepness that Spiderkind can depend on? Pedure, there is a deepness in the sky, and it extends forever."
Time Scout: The first and third books don't count, as the first, Time Scout names the profession that is the focus of the series and the third, Ripping Time names the period of time that is the focus of the last two books. The third, Wagers of Sin is only dropped in the description on the back cover. The last one, The House That Jack Built is dropped in the epilogue in a rather gratuitous fashion.
An Isaac Asimov short story "In Poor Taste" ends with the main character, who is right, but exiled from his planet nonetheless, hearing form his mother that "what you did was in..." then the shuttle doors close, muffling out the last three words.
The Dead Souls by Nikolai Gogol aren't souls in the religious sense, they're not immediately mentioned, and it takes even longer for us to learn what's the real purpose of the protagonist buying them up.
The Madness Season is the portion of the Tyr life cycle where the Raayat drones gain a sense of individuality apart from the Hive Mind as they prepare to mate with the queen.
In Kiss of the Spider Woman by Manuel Puig, Molina recreates movie plots to his cell mate Valentin to pass the time. The first one is about a panther-woman who kills every man who kisses her. Later in the book, after both prisoners start having an affair and Molina is set free, Molina asks Valentin why he hasn't kissed him yet. He answers jokingly that he was afraid he'll became a panther and kill him, like the panther-woman movie, to which Molina replies that he is not a panther-woman. Valentine then says to him: "You are the spider-woman, who catches the men in her web" and Molina says that he likes that. At the end of the book, when Valentin starts having a death dream, the title is dropped again reinforced with the image of the spider-woman when he is talking with Marta.
In John C. Wright's Count to a Trillion, Blackie starts making plans at once for a far future danger, on the grounds that even if a man does not have the patience to count to a trillion, still the number exists.
In Teresa Frohock's Miserere: An Autumn Tale, one character says "Miserere" — have mercy — as a plea for mercy for himself, and another sends a letter instructing John that a lost sheep is returning, and concludes with it Miserere.
In Zero History by William Gibson, Defence Criminal Investigative Service agent Winnie Tung Whittaker is telling Milgrim how little of a trail he has left over the years: "Zero history as far as Choice Point is concerned. Means you haven't even had a credit card for ten years."
Played with in Paul Murray's novel An Evening Of Long Goodbyes. About halfway through the book, the narrator character decides to write a play based on the events happening around him. He says he has chosen the title: six words which perfectly capture the sad mood of the situation. The next chapter is the playscript itself, titled There's Bosnians In My Attic! The trope is played straight elsewhere, where "An Evening of Long Goodbyes" is the name of a racing greyhound.
Used incessantly in Fifty Shades of Grey and its sequels, where Ana Steele regularly drops variants of the title and its sequel into her narrative, talking about herself as being so many shades of confused, a situation being many shades darker, and so on. She also refers to the male protagonist, Christian Grey, as "Fifty Shades," "her own personal Fifty Shades", etc. It amounts to in-universe advertising.
The protagonist of Heavy Metal and You by Christopher Krovatin drops the title as the only two things he has.
The Statistical Probability of Love at First Sight by Jennifer Smith approaches the second variety of Title Drop, using it on the next-to-last page.
A Brother's Price: Jerin Whistler, the oldest son in his family, is approaching the age of marriage, when he is to be sold for his brother's price, a custom very like a bride price. His family strikes a deal to buy a shop with the money they get from him, and he's very conscious that he has to sell high so they don't have to renege on that deal and pay a penalty.
In Philip Friedman's trial novel, Inadmissible Evidence, the main character tries to get some witness testimony admitted. After judge throws it out, and the trial is about to start, we get this nice little passage:
The morning papers gave him even less space, mostly playing the story as an implausible allegation properly kept out of court. They seemed more willing to show their bias in favor of [the defendant] now that the trial was about to begin. Only one treated [the witness's] story as seriously as Estrada thought it deserved.
The front page headline in Noticias Diarias said simply, PRUEBAS PROHIBITAS. Inadmissible Evidence.
A Christmas Carol: "There was a boy singing a christmas carol at my door last night..."
In Joseph Heller's Catch-22, the title (The Catch-22) is one of the main satirical points of the book, depicting a situation in which a favourable solution is made impossible by illogical rules.
Brewsters Millions: At some point in the original book, when Montgomery Brewster was quite close to receiving "Sedgwick's Millions", he said they'd soon become "Brewster's Millions".
In the prologue for the fifth book of Power of Three, Rock makes a reference to "the power of three". In Sign of the Moon, which isn't even in the Power of Three series, when Jayfeather realizes that Lion's Roar and Dove's Wing are past incarnations of Lionblaze and Dovewing, he says that the "Power of Three" (capitalized like a title) has begun.
In Omen of the Stars, Yellowfang mentions "an Omen of the Stars" (also capitalized like a title) in the prologue of the very first book.
There are no less than three echo related metaphors used in Fading Echoes.
The Last Hope takes the cake. It gets dropped at least five times in the book, two of them from the prologue alone.
There's a belated, sort-of Title Drop in The Hunger Games trilogy: "hunger games" and "mockingjay" appear all throughout the trilogy, but in Mockingjay, Katniss proclaims that "fire is catching". Catching Fire was the previous book.
All of Dennis Lehane's Kenzie/Gennaro novels feature this; the title of each book is dropped at some point either in character dialogue or through Patrick's narration.
Early on in Elizabeth Gaskell's North and South, Nicholas Higgins remarks, "And yet, yo' see, North and South has both met and made kind o' friends in this big smoky place".
The titles of most of the later Black Company books are dropped as Arc Words. The Silver Spike deals with the fate of said Artifact of Doom. Bleak Seasons is used in that book and Soldiers Live as a metaphor for anguish felt at loss of loved ones in wartime. She is the Darkness is repeated again and again by the wizard Smoke in regard to the series' most prominent female characters. Water Sleeps comes from the graffiti that spread over the city of Taglios, itself shorthand for the expression, "Even water sleeps, but enemy never rests." Soldiers Live is short for "Soldiers live, and wonder why," a metaphor Croaker uses to explain his survivor's guilt over all the Company men and women he outlives.
The Seymours' estate Wolf Hall is mentioned a few times towards the end of Wolf Hall, its name being a metaphor for the Tudor court as a whole as well as an indication of what will happen in the sequel.
Tortall Universe: Most of the that are spoken in the text are nothing out of the ordinary, but some do have thematic significance.
Song of the Lioness: The third book, The Woman Who Rides Like A Man, is a title that the Bazhir give former Sweet Polly Oliver Alanna when she becomes their shaman. She takes exception and says that women and men aren't all that different—men just have more ego.
Protector of the Small: The individual books have Exactly What It Says on the Tin titles, but throughout the quartet we see Kel helping and protecting various defenseless people or animals. In the final book, she's finally called "the Protector of the Small" by a seer who foretold her coming to Scanra to save refugee children. Kel finds it a bit of an Embarrassing Nickname.
Provost's Dog: Provost's Dogs are slang for the guard (i.e. police) and each book is titled after a breed. Beka, the protagonist, ends up nicknamed as each of them—"Terrier" for not letting go of cases nobody expected to solve, "Bloodhound" for following the trail of counterfeit cash relentlessly, and finally "Mastiff."
