''When Rabbit Howls'' is a 1987 autobiography by "The Troops" for Truddi Chase (being the collective name for the author's multiple personalities). The novel details her journey through therapy as she discovers dozens of personalities living within her, and unlocks the horrors of her childhood that caused her mind to fracture over and over again.
!!This novel provides examples of:
* AbusiveParents: The Stepfather, although the Mother dished out a fair share of physical and emotional abuse.
* AlphaBitch: Catherine was created to be a strong, dominant personality who could force the Troops into line.
* AwesomeMcCoolname: Many of the personalities have these--Ten-Four, Nails, The Seventh Horseman, The Zombie, and Miss Wonderful, among others.
* [[spoiler: CallingTheOldManOut: At the end of the novel, the Troops arrive ''en masse'' on the Stepfather's doorstep, in their own bodies, to deal out their revenge. Turns out it was AllJustADream, though.]]
* [[CreepyChild Creepy Children]]: The little ones in the Troop formation are very damaged, very angry, and hungry for revenge.
** One child manifests as an eyeless creature frozen in a block of ice. Another child presents herself to The Woman by slipping up and silently staring at her.
* DisabilitySuperpower: One of the most controversial aspects of the book is Chase's apparently ability to interfere with electronic devices with her mind, [[HandWave handwaved]] as the electronic feedback of many minds coming and going at once. She also allegedly displayed mild precognitive and mental domination abilities.
* EyeColorChange: Frequently occurs when a different personality emerges.
* FightingIrish: Eon presents himself as the reincarnation of an ancient Irish warrior and is implied to be a remnant of one of Chase's past lives. The less mystically minded interpret Eon as an internalized version of Truddi's beloved Irish grandfather.
* GenkiGirl: Elvira/The Outrider, a laidback sarcastic personality who loves loud music and partying.
* GoodBadGirl: Sixteen was created to deal with the normal sexual feelings of adolescence that under the circumstances were horrifying and distasteful to the other Troops. She is described as a teenage girl with "enough sexual knowledge to run a bordello" but who also manages these feelings in a rational, normal way.
* MyNaymeIs: Little Lambchop variously spells her name as Lambchop, Lamb Chop, and Lamchop.
* OneSteveLimit: Subverted. Among the personalities is Catherine, Lady Catherine, Sister Mary Catherine, and Black Katherine.
* PapaWolf: Mean Joe.
* PuritySue: Played straight. Miss Wonderful is literally incapable of sexual thoughts and has no memory of any sexual experiences.
* TheIngenue: Twelve is a savvy twelve-year-old genius who is able to comprehend and explain the Troops' internal mechanisms, as well as being artistically and socially gifted.
* SharkPool: As a punishment her sadistic stepfather [[spoiler:lowers her into a well infested with snakes. The trauma of this single event finally pushes her over the edge and she begins to split off her personalities to deal with her abuse.]]
* SirSwearsALot: The appropriately named Sewer Mouth, who vents her anger through loud, frequent, and extremely creative cursing.
* SplitPersonalityMerge: The Troops refuse to do so.
* SocialServicesDoesNotExist: Justified, as at the time of Chase's abuse (the mid-to-late 1930s through 1950), social services and child welfare agencies as we know them really ''didn't'' existed.
* SternNun: Sister Mary Catherine seems to have been created both as a response to The Mother's hypocritical Irish-Catholic religion and as a manifestation of the Troops' own guilt and self-blame. She is rarely seen, but "evidences" as the sound of rosary beads clicking.
* TalkingToThemself: The author's various personalities have internal conversations with each other.
* ThereAreNoTherapists: Subverted twice. Not only is Chase's therapy an important part of the overall narrative, but we learn that The Woman has sought out therapists multiple times over the course of her life, only to either be misdiagnosed or so frightened by what she learned that she quit.
* TheVoiceless: Rabbit only screams in pain and horror.
* TheWatson: The police detective with whom Stanley discusses the case was created for the book as a way to discuss both therapy details and information about child abuse. He did not exist in real life.
* WomanInBlack: Black Katherine, a fearsome personality, presents as this.
