It is not a horror book, more of a "slice of life" book written to be realistic. It's based during the times of Slavery.
Atticus Finch is a lawyer who was assigned to defend a black suspect in a murder case. It does not get down-and-gritty horrifying; more-or-less it is just a slice-of-life story told from a viewpoint of a little girl.
And btw PyramidHead, for clarification, the book is called To Kill A Mockingbird.
And I hated the book, just as I hated The Giver and a few other books I was forced to read. Though, now that I think of it, it wasn't too bad really. Gotta give every book some credit.
