Monster
Steve Harmon is a 16-year-old who has been accused of being an accomplice in the murder of a convenience-store owner in Harlem. An aspiring filmmaker, he decides to document his experiences and record everything that happens to him, from his appearances in court to the atrocities of jail. The book asks readers to be both a witness and a juror, and to try to decide for themselves whether Steve is being misused as an police informant, or innocent of the charges against him. Incidentally, Steve decides to call his movie MONSTER, the label the prosecutor tagged him with during a hearing. Nominated for a 1999 National Book Award in the Young People`s Literature category, a 2000 Coretta Scott King Author Honor Book, and winner of the 2000 Michael L. Printz Award for Excellence in Literature Award.
