''The Final Reflection'' is a 1984 novel in the Franchise/StarTrekExpandedUniverse, written by Creator/JohnMFord.

In the prologue, Captain Kirk notices odd behaviour in his crew returning from shore leave. When he asks Dr [=McCoy=] for an explanation, [[NestedStory [=McCoy=] hands him a book...]]

''The Final Reflection'' is a historical novel, recounting events of forty years earlier, at a time of crisis for the Federation. Its hero is a bold and intelligent officer who rises from obscure origins to captain a starship, and finds himself the right man at the right time to save the Federation from destruction.

His name is Krenn, and he is a Klingon.

!!This novel provides examples of:

* ActualPacifist: The diplomat Emanuel Tagore. This causes some confusion when Klingon security attempts to search his luggage for hidden weapons, and takes their inability to find any as a sign that he's hidden them really well.
* AerithAndBob: After joining the navy, [[MeaningfulRename Gelly becomes Kelly]]. During a layover at a Federation starbase during the first peace mission, some Starfleet personnel joke that there's an Irishman on the Klingon crew.
* AllThereInTheManual: The Klingon-centered boxed expansion set (creatively titled ''[[ExactlyWhatItSaysOnTheTin The Klingons]]'') that Ford worked on for [[{{Creator/FASA}} FASA's]] ''Star Trek'' TabletopRolePlayingGame expanded on many things mentioned only in passing in the book (such as the Klingons' rank structure, their battles with the [[KnightTemplar relentless]] [[StarfishAliens Kinshaya]], and [[DoomsdayDevice how]] [[FromNobodyToNightmare Ford's version of Kahless the Unforgettable]] created a unified Empire and led it to the stars).
** Other bits of history and technology (such as the ''Mann''-class starships and the hijacking of the ''Flying Fortress'' by Klingon privateers under Kethas's command) came from the ''[[https://en.wikipedia.org/wiki/Star_Trek_Spaceflight_Chronology Star Trek Spaceflight Chronology]]'', one of the first semi-canonical attempts to delineate the Federation's history.
* AttackItsWeakPoint: After a bar fight, a Klingon medic complains about Humans liking to punch people in the jaw (and by extension, all the dislocated jaws he had to fix).
* BasedOnATrueStory: The novel-within-the-novel claims to be this, in-universe. How closely or accurately it's based on the truth is left unclear.
* BigBrotherIsWatching: Imperial Intelligence is always watching (or, at least, might at any given moment be watching, which is practically the same thing).
* BigFancyHouse: Maxwell Grandisson [=III=] lives in the Hyatt Regency Hotel in Atlanta...not as, say, a long-term guest in the penthouse suite, but as its owner and sole occupant (apart from his staff). Doubles as an OldDarkHouse as over the centuries (it opened in 1967), the windows have gone opaque with age.
* BlackmailIsSuchAnUglyWord: A Rigellian delegate at a conference attempts to sway Krenn's delegation with an offer of substantial "administrative expenses", and protests when Krenn prefers to call it "bribery".
* CallBack:
** Philanthropist Carter Winston from the ''WesternAnimation/StarTrekTheAnimatedSeries'' episode "The Survivor" appears.
** A subtle one in the TOS episode [[Recap/StarTrekS3E7DayOfTheDove "The Day of The Dove"]], Klingon transporters are seen operating with a different color pattern and without the characteristic screeching sound. Instead of waving it off as [[SpecialEffectsFailure a mistake]], Ford took this and ran with it, indicating that the sound from Federation transporters came from a secondary carrier wave added to provide a bit more safety; the ever-practical Klingons decided a silent transporter was more valuable than a one percent decrease in errors.
* CavalryBetrayal: [[spoiler:Inverted]] at the end of the book, as [[spoiler:Krenn swoops in with his SuperPrototype dilithium-powered battlecruiser to intercept a Klingon bombardment fleet sent by a pro-war faction of the Imperial government to destroy a Federation colony]].
-->"[[spoiler:Captain Krenn]]? I...was not told you were in this sector. Are you not commanding the...diplomatic mission?"\\
"I was. But no longer."\\
"Then you may join us," [[APupilOfMineUntilHeTurnedToEvil Kian]] said, excited. "There will be high glory--"\\
"No," [[spoiler:Krenn]] said, "you are mistaken." He turned to ''Mirror'''s Weapons officer, spoke a phrase of Battle Language.
* CharacterizationMarchesOn: At the time this novel was written, almost no details had been revealed about Klingon history, language and culture in the screen canon, so Ford invented his own -- which were largely ignored and frequently contradicted by subsequent movies and TV episodes, leaving the novel out of step. (Particularly noticeable in the case of the Klingon language; Ford's ''klingonaase'' bears little resemblance to the ''tlhIngan Hol'' later created by Marc Okrand for the movies.)
* ChildhoodFriendRomance: Krenn and Kelly.
* DeceasedFallGuyGambit:
** The novel-within-the-novel opens with a competition between teams representing the Klingon Navy and Marines, with their InterserviceRivalry meaning a signficant amount of prestige rides on the outcome. When the team representing the Marines is found to be cheating, the Marine officer in charge of the team is blamed for the whole thing and executed on the spot by a superior officer who, it is implied, is at least a co-conspirator and probably the real mastermind.
** An officer on Krenn's ship attempts a mutiny, during which another officer is seriously injured. The mutineer attempts to convince Krenn that he's too useful to do away with, and suggests that the injured officer could easily be converted into a deceased fall guy.
* DramaticDrop: A porter at a hotel on Earth drops the tray he's carrying when he sees a group of Klingons passing by.
* ExpospeakGag: After a human diplomat makes a proposal that Krenn finds horribly insulting, he relieves his feelings by using an alien language the humans don't know "to curse the Humans and their riding animals".[[note]]"--and the horse you rode in on!"[[/note]]
* FakeStatic: An ensign under Krenn's command tries a version of this on Krenn, who is amused by it but isn't fooled for a moment.
* {{Fiction 500}}: Maxwell Grandisson [=III=], a man rich enough to make his home in a high-class hotel -- as the sole occupant -- and powerful enough to ask for and get a personal meeting with Krenn and his subordinates. Although interested in making peace with the Klingons, he gives the impression of someone who is used to getting his way in all things; according to [[ColonelBadass Colonel Rabinovich]] he's an [[PoliticallyIncorrectVillain anti-Semite as well]].
* {{Fictionary}}: "Klingonaase", the Klingon language featured in ''The Final Reflection'' and the FASA role-playing game.
* FramingDevice: The bulk of ''The Final Reflection'', the real-life tie-in novel, is the text of ''The Final Reflection'', the 23rd-century historical novel, framed by a prologue and epilogue in which the regular ''Trek'' characters read and react to it.
* GeneticMemory: Mention is made of learning languages by "RNA transfer"; it's hinted that the RNA in question comes from captured Federation citizens.
* GenghisGambit: [[spoiler:The novel-within-the-novel includes a claim that, at a time when the member states of the Federation were considering going their separate ways, the Chief of Staff of Starfleet authorized secret attacks on his own fleet's ships that could be blamed on the Klingons and used to give everyone a common enemy to focus on.]]
* GoingDownWithTheShip: The captain of a Klingon warship is free to send his crew to safety before the ship goes kablooey, but is expected to remain behind himself. (The saying "Kahless's Hand" refers to the first Klingon emperor, who tied his hand to his command chair so no one could say he'd ducked out.)
* GRatedDrug: High-sugar foods (such as fruit juices) to Klingons, as their metabolism breaks it down quickly while giving them a mild rush.
* HalfHumanHybrid:
** Ford's answer to the notorious Klingon Forehead Mystery is that the Klingons created half-human hybrids the better to understand (and therefore to fight) humans, and likewise half-Romulans, etc. Krenn's love interest Kelly is such a hybrid, but doesn't know what her non-Klingon half is, which complicates medical treatment and rules out having viable offspring.
** There is also, of course, Spock, the original ''Star Trek'' half-human hybrid. The novel-within-the-novel hints in passing that the Vulcan medical science that made his conception and birth possible may have been stolen from the Klingons.
* HistoricalDomainCharacter: The novel-within-the-novel has several historical figures in it, including a cameo appearance by a young Spock and his parents. (In the frame story, the real Spock is visibly unhappy about the novel, and refuses to talk about whether the scene has any basis in truth.) [=McCoy=]'s grandfather has a small but significant role, and at one point compares one of the novel's antagonists to the contents of "my grandson Leonard's diapers".
* HistoricalFiction: The novel-within-the-novel.
* HumanChess: Although technically the participants are all Klingons and the game is ''klin zha'', specifically ''klin zha kinta'', 'the game with live pieces'.
* InterserviceRivalry:
** Strong between the Klingon Navy and Marines.
** Starfleet and Federation Marines apparently also have this going on. A brawl starts when a Starfleet officer tells some Klingons his name is Marks, and a Klingon responds that he knows many Klingons named Marks, and they're all Marines.
* IWasNeverHere: At one point, Krenn is hauled off in the middle of the night by Imperial Intelligence (who were never there) to a meeting (which never took place).
* KlingonScientistsGetNoRespect: Averted. Krenn's science officer is his first officer and he describes the Sciences as an Honourable option to the young Spock.
* LightbulbJoke: "Rom Jokes", which Federation and Klingon crewmembers swap en route to a peace conference. The only one related to the reader is "How many Romulans does it take to change a transtator coil? Answer: 1 to change the coil, 150 to blow the ship up out of shame."
* LockedInAFreezer: Krenn and two loyal subordinates are locked in his ship's walk-in freezer by a traitor. The situation is even more serious for the hero than usual because Klingon biology is keyed to very warm temperatures (he was more annoyed by the dryness at the White Sands spaceport than the heat), which makes them very susceptible to frostbite.
* MeaningfulRename: The protagonist of the novel-within-the-novel goes through several. One is the rename all Klingons do when they determine their life career path. Klingons entering the Klingon Navy, as Krenn does, have a name beginning with K; Marines have names beginning with M; civilian scientists and technicians have names beginning with A; and so on.
* MercyKill: The only kind [[spoiler:Tagore]] has ever performed. [[spoiler:On his wife]].
* MustHaveCaffeine: In the novel-within-the-novel, a sympathetic Klingon character is depicted as a morning coffee drinker, praising its mind-clearing effect; it's explained that he picked up a taste for it during a space voyage where the supplies ran low and all they had to drink was a case of "kafei" they'd plundered along the way.
* OpeningTheFloodGates: When Tagore hears combat outside of his stateroom on the ship taking him to the Klingon homeworld, he opens the hot-water taps in his bathroom, closes the door, and hides under the bed. When his assailant barges into the bathroom he gets a face full of scalding water, distracting him long enough for Krenn and Kelly to take him out.
* OrangeAndBlueMorality: The Klingons' expansionist and conquest-driven culture is based on their belief that all life is divided into ''komerex'' (literally "the structure that grows") or ''khesterex'' ("the structure that declines"); any culture that doesn't continue to grow and develop is regarded as a failure and fit only to serve its betters. Underlining this, their own name for their society, though usually translated as "Klingon Empire", is ''Komerex Klingon''. They have some difficulty figuring out which of these the Federation is.
* PardonMyKlingon: Done with actual Klingon swear-words.
* SealedBadassInACan: The [[spoiler:Klingons]] have a super-soldier with enhanced reflexes that makes him practically unbeatable, at the cost of a dramatically reduced lifespan. To get the most possible use out of him, his handlers keep him in cryogenic suspension between missions.
* ShoutOut: Tagore's library includes ''Literature/SpaceCadet'', ''[[Creator/MarkTwain The Innocents Abroad]]'', and ''Literature/TheOnceAndFutureKing''.
** ''Latrunculo'', a Romulan game similar to Klingon ''klin zha'' and Human ''chess'', is (more or less) the name [[https://en.wikipedia.org/wiki/Latrunculi of an actual Roman strategy game]].
* SleepLearning: Klingons have a version of this, "dream learning", which Krenn uses to learn to speak Federation Standard rather than rely on the proto-Universal Translator. It's effective but not pleasant, because it interferes with proper dream sleep and results in disturbed and unrestful sleep.
* SmartPeoplePlayChess: Klingon military strategy is the province of military "Thought Admirals", who hone their skills in ''klin zha'' (Klingon chess). Krenn's Thought Admiral foster-father also studies other races' equivalents of ''klin zha'', including the Human game ''chess'', to gain insight into the races that play them.
* TheSpymaster: Operations Master Meth, the head of Imperial Intelligence.
* TeleporterAccident: "Scramble cases" were noted as having occurred when Klingon personnel were beamed off a heavily damaged ship during a raid on a Romulan colony.
* {{Trilogy}}: The story has three sections, each one covering a different period of Krenn's life. In addition, each section has three chapters.
* {{Tuckerization}}:
** The author's note at the beginning of the novel-within-the-novel includes a message of gratitude to "Mimi Panitch, my editor, who first decided the Federation was ready for this story"; in real life, Mimi Panitch was the editor at Pocket Books who brought ''The Final Reflection'' to print, along the way defending it from Paramount higher-ups who doubted its suitability.
** It also includes cameos by Klingons based on the co-authors of the Klingons sourcebook for FASA's ''Star Trek: The Role-Playing Game''; many of the details of Klingon history and culture that appear in the novel also appear in the sourcebook, which Ford helped develop.
* TwoDSpace: Krenn notices that a group of Romulan ships his ship is fighting move in a plane, then recognises the patterns in their movements and infers that their commander is visualising the battle as if it were a game of ''latrunculo'', the Romulan equivalent of ''klin zha''.
* UnfortunateName: [[PrematurelyBald Rogaine]], [[GreenSkinnedSpaceBabe the Orion concubine]] of Krenn's foster father. The name was a coincidence, as [[https://en.wikipedia.org/wiki/Minoxidil minoxidil]] wasn't approved for topical use as a hair restorer until 1988.
* UnreliableNarrator: The novel-within-the-novel begins with an author's note admitting up-front that some of what follows is no more than informed speculation, and some of it just plain made up to paper over the gaps in what his research was able to uncover. He declines to say which bits are which.
* TheUnreveal: When the half-Klingon Kelly finally learns what the other half of her parentage was, the reader doesn't. (Dramatically speaking, the important thing is ''that'' she knows, not ''what'' she knows.)
* VariantChess: Krenn's father studies other races through their chess-equivalents. Of the several mentioned in the novel, ''klin zha'', the Klingon game, is of particular and recurring significance, with several variants of ''klin zha'' described, each having its own significance to the book's themes.
* VillainEpisode: For the Klingons.
* WarriorHeaven: The Klingons believe in an afterlife in which great warriors are awarded places in the Black Fleet, where they fight and die and are revived and fight again against the great warriors of other races (because what good is a warrior heaven with nobody to fight against?).
