->''I am Ariel, the Adopted.''

Written by hardboiled detective author Lawrence Block and marketed as a horror novel, ''Ariel'' is a very subtle story about the scapegoating of a "different" child, communication failure and the destruction of a family, with supernatural elements crawling in at the windows.

Ariel Jardell is thirteen years old and a bit too perceptive for her own good. Now that her mom Roberta has had a child of her own, she's ready to dispose of Ariel, and Ariel knows it. Her father David is well aware the little boy, Caleb, is not his and that Roberta has been seeing an old boyfriend, lawyer Jeff Channing. One night, Roberta has a strange dream, and wakes to find that Caleb has suddenly died. And Ariel takes one look at her and says ''Is Caleb dead?''....

!! Provides examples of:
* AbsentmindedProfessor: Mr. Wold, the father of Ariel's friend Erskine, may be a teacher (as his wife is); certainly he's extremely absent-minded and preoccupied. When Erskine half-jokingly suggests Ariel move in with him to avoid leaving the neighborhood, he claims "My father could live in the same house with you and never notice you were there. At dinner you could ask him to pass the salt and he'd pass it and ''still'' not notice."
* TheAlcoholic: David becomes a functional one of these. But he also loves Ariel, so things may work out for him. Roberta is hooked on prescription sleeping pills.
* TheBeautifulElite: Jeff Channing comes very close to being one of these. Ariel and Erskine say "he's got those television good looks."
* BlackComedy: Erskine is fond of this.
* {{Bookworm}}: Ariel. She's got all the Oz books, plus young-adult novels, and cites several books she loved but didn't finish, including Rosalyn Drexler's ''I Am The Beautiful Stranger''. She's also read at least some of ''Literature/MobyDick'' and actually did finish Poe's ''Literature/ThePurloinedLetter'', which is where she gets the idea to [[HiddenInPlainSight keep her diary in a school notebook]]. (She talks about knowing better than to keep it in one of those ''[[SecretDiary My Secret Thoughts]]'' books around Roberta.) Creator/SylviaPlath and ''her'' book ''Ariel'' are mentioned several times.
* CreepyChild: Roberta thinks Ariel is. Also, Ariel's klutzy friend Erskine Wold. Ariel hints that Erskine may turn out to be BeautifulAllAlong behind those NerdGlasses: "What he should really do is get contact lenses when he's older. His eyes are really quite attractive." Jeff, observing Ariel walking home from school, thinks she might be beautiful as she matures.
* DeadpanSnarker: Ariel, and Erskine has some of this too.
* DreamingTheTruth: Ariel may have done so, but she may also be dreaming what she fears or what her mother thinks happened.
* DrivenToSuicide: [[spoiler: Jeff and Roberta]].
* EvilOrphan: After Caleb's death, Roberta is completely convinced Ariel is this. She even suggests at one point that Ariel might be the offspring of a Manson-like cult. Her obsession infects Jeff, [[spoiler: with fatal results for both of them]]. By book's end, Ariel hints that she might believe it herself, especially after [[spoiler: what she had to do to prevent Jeff from murdering her]].
* GameShow: After seeing Jeff (not knowing who he is) at Caleb's funeral, Ariel begins to think of him as a host for ''Series/TheDatingGame'', then imagines a new show, ''The Funeral Game'' -- pick the right coffin and win an all-expenses-paid trip for two to Forest Lawn.
* HauntedHouse: Itself a character in the story. Ariel's family has just moved into the big old house at 42 Legare Street, in an older section of Charleston, South Carolina. While Ariel loves it, Roberta comes to believe it is conscious and evil.
* HellIsThatNoise: Ariel's flute, to Roberta -- but especially at the climax.
* HeyYou: Roberta rarely uses Ariel's name. She speaks of "the child".
* InterplayOfSexAndViolence: Jeff and his, er, gun.
* MagicalFlutist: A spooky version thereof. It's never described just where Ariel got her tin flute. She plays it all the time. David enjoys it as did little Caleb, but Roberta hears it as HellIsThatNoise. Or maybe Ariel is just a DreadfulMusician -- but at the end, combined with another instance of communication breakdown, it's [[spoiler: what finally drives Roberta to suicide.]]
* MaybeMagicMaybeMundane: It's left ambiguous whether there really is something supernatural about the house or whether the events are just a result of the insanity of the people involved.
* MindControlEyes: Ariel learns to make people who fear her obey her by "making her eyes look like those of the lady in the portrait" she's found.
* OutOfClothesExperience: Ariel lights candles and contemplates the lady in the portrait. She begins to do it without being aware she's doing it, and when she comes out of it she's naked and being yelled at by Roberta.
* PaterFamilicide: [[spoiler:Jeff eventually kills his wife and children before killing himself]].
* PoorCommunicationKills: The novel's main theme.
* PsychicChildren: Jeff suggests that Ariel might have some psychic ability and could have sensed Caleb's death without Roberta having to say anything. (Roberta thinks Ariel said "Is Caleb dead?" because she killed him. Ariel tells Erskine that she knew Caleb was dead from the look on Roberta's face as she left his room.)
* PuppyLove: Ariel and Erskine, although they agree they don't want to "do that" [[IDontWantToRuinOurFriendship because they're friends]]. The author says that their scenes together are his favorites, and he's very fond of them.
* SanitySlippage: First Roberta, then Jeff, both becoming obsessed with Ariel.
* SecretDiary: Kept in an ordinary school notebook so Roberta won't snoop, and it works; it remains safe throughout and at the end, while Ariel says she hasn't felt like writing in it since [[spoiler: Roberta's suicide]], it's open ended and she may return to it at any time.
* {{Sleepwalking}}: Everyone in Ariel's family does this at some point, either because they're tired, drunk, or.... something else.
* SpookyPainting: Found in Ariel's attic and "adopted" by her. May or may not be a portrait of Grace Molineaux, who may or may not have been an AxCrazy murderess and/or Ariel's ancestor or former reincarnation.
* UnableToCry: Ariel, in front of people. Part of the communication breakdown is caused by Roberta's belief that Ariel never cried for her brother. She actually did, but alone in her bedroom.
