''Extremely Loud & Incredibly Close'' is a 2005 novel by Jonathan Safran Foer (of ''Literature/EverythingIsIlluminated'' fame). The book is written in multiple viewpoints. The majority is in the first person, and is told by Oskar, a 9-year-old boy. Between chapters are letters written by Oskar's paternal grandparents, detailing how they met and eventually separated.

The book is written in AnachronicOrder, starting in the present and then going back two years detailing how the story got to that point. The story follows Oskar, whose father died during the 9/11 attacks. Oskar and his father used to play a game called "reconnaissance expedition", in which Oskar would be instructed to find a variety of objects. A year after his father's death, Oskar finds a key in an envelope which has the name "Black" written on it. He believes these are clues and are part of an expedition that his father was planning, and makes it his life's goal to discover the meaning behind it.

It has since been adapted into a 2011 film directed by Stephen Daldry, starring Creator/TomHanks, Creator/SandraBullock, Creator/ViolaDavis, Creator/MaxVonSydow and Creator/ThomasHorn as Oskar. It was nominated for Best Picture and Best Supporting Actor (Von Sydow).
!!''Extremely Loud & Incredibly Close'' provides examples of:

* AdaptationDistillation: While many of Oskar's quirks remain in the movie (his tambourine playing, his ambiguous autism, etc.), some of his more annoying qualities were removed. His obsession with all things white (food and clothing), his pretentiousness, and the sadistic thoughts he has about his classmates are all absent in the film. Oskar also [[spoiler: [[EarnYourHappyEnding earns his happy ending]]]], as opposed to the book, which ended on a decidedly more depressing note.
** In addition, the story of Oskar's grandparents is completely left out, with his grandfather's [[spoiler: voicelessness]] chalked up to witnessing a bombing back in World War II.
* AmbiguousDisorder: Oskar regularly sees a therapist who confesses to his mother that he thinks Oskar should be institutionalized.
* ArsonMurderAndJaywalking: Oskar imagines himself getting back at Jimmy Snyder during their performance of Hamlet for bullying him:
-->'''Oskar''': You are guilty of having abused those less strong than you: of making the lives of nerds like me and Toothpaste and The Minch almost impossible...And I've seen you litter, too.
* BigApplesauce
* BrickJoke:
** Oskar promises to donate his pocket money towards diabetic research for lying to Abby Black. Chapters later, he receives a letter thanking him for the 50 cents he donated.
** The taxi driver Oskar shortchanges. He's not mentioned again until he sends Oskar a letter thanking him for actually paying him back.
* BrokenRecord: Oskar's private lexicon: the elliptical verbal tics of a {{Cloudcuckoolander}}, not [[MadnessMantra Madness Mantras]]. Such as the "heavy boots" of grief slowing Oskar's progress, searching through the [[DontExplainTheJoke five remaining boroughs]] for the owner of the [[MacGuffin key]]. Or using "José!" to mean "You can't be serious!" (omitting "No way..." from the exclamation).
* CreepyChild: Sometimes Oskar's behavior goes way beyond NoSocialSkills. He brought in a recording of a man recalling, in gory detail, the bombing of Hiroshima for his ''elementary school class'' to listen to, he dropped his cat off the school roof (he knew the cat would be fine, but his classmates sure didn't), and he fantasizes about beating some of his classmates to death.
* DeadGuyJunior: Oskar's father is given the name Thomas Schell by Oskar's grandmother. Thomas Schell senior is dead only in the sense that he feels he cannot live, but is as good as dead due to his absence.
* DisappearedDad: Oskar's grandfather Thomas to his father, also named Thomas. His letters, which are all titled "Why I'm Not Where You Are", are addressed to Oskar's father, and in them the elder Thomas apologizes and explains why he wasn't in his son's life.
* GraveRobbing: Oskar and the renter dig up Oskar's father's coffin. Subverted in that there's no corpse.
* HideYourPregnancy: An in-universe example. [[spoiler:One of the "rules" that Oskar's grandparents made was to never have children, but his grandmother felt she was losing him, so she made a pregnancy happen anyway and hid it with baggy clothing and pillows. Still didn't stop him from leaving.]]
* KillEmAll: During the bombings in Dresden, Grandpa comes across a zoo, and the keeper asks him to shoot everything...which includes the normally harmless animals. Would be a MoralEventHorizon, except that the animals most likely would've eaten human corpses if they were left alone, plus Grandpa felt guilty enough about the event that he bought tons of animals for his apartment after he relocated to New York.
* MeaningfulName: Schell is derived from a German word meaning 'noisy' or 'loud', an allusion to the title. However, it is also an ironic reference to Oskar's grandfather's inability to speak due to trauma, and Oskar's own problems in dealing with his grief.
* MostWritersAreAdults: On one hand, it's easy to believe that Oskar's mannerisms are framed by adult author ideals. On the other, he's a child coping with a terribly traumatic event, and it's acknowledged in universe that this, coupled with his intelligence, makes it difficult for him to make friends (and in reality, there are plenty of children in who act like Oskar).
* UsefulNotes/NaziGermany: Where and when Oskar's grandparents grew up.
* NeverFoundTheBody: Oskar's father's body was never found in the aftermath of 9/11. His funeral at the start bothers Oskar for the fact that there's no corpse in the coffin they're about to bury.
* NoNameGiven: Oskar's mother and grandmother are never named, and he refers to them only in those terms.
* NoSocialSkills:
** Some of the games Oskar and his father played involved Oskar being forced to speak to people, because his father wanted Oskar to get better at it.
** Despite having gained self-control with maturity, Oskar's father was NotSoDifferent: as Mom (with mixed feelings) recalls, frequently.
* OscarBait: A DoubleSubversion. Despite being critically drubbed upon release, it still somehow got a Best Picture nomination, almost purely for its subject material. Creator/MaxVonSydow's nomination was almost entirely chalked up to the fact he was a Hollywood institution whose Oscar was sorely overdue, and he might have won had he not been up against the similarly overdue Christopher Plummer.
* PresentDayPast: Movie only- A 2008-up Ford Escape with the "NYC'''T'''AXI" logo introduced in 2007 is prominent in the trailer's first street scene. Overlaps into AnachronismStew - Oskar's dad films him on Super 8 rather than the then-common VHS-C.
* SelfHarm: Oskar frequently bruised himself when he was upset.
* TwoLinesNoWaiting: The alternation between Oskar's plotline and that of his grandparents.
* UnusualEuphemism: Oskar's mother forbids him from using profanity, which leads to the phrases 'Dipshiitake', 'Fukuzawa you', and 'succotash my balzac'.
* TheVoiceless: Oskar's grandfather Thomas. After [[spoiler:Anna's]] death, Thomas slowly loses the ability to say certain words, until eventually he can't say any.
* YouRemindMeOfX: The only reason Oskar's grandparents got together is that [[spoiler:his grandmother reminded Thomas of Anna, her sister and his first love]].
* YouShouldHaveDiedInstead: Oskar sometimes feels this way about his mother and even says it at one point, but he immediately regrets it.
