Someday

While A is inhabiting the body of a bullied teen named Moses, the boy is beaten mercilessly by classmates and taken to the hospital. Another character, X, hurts others with the bodies he inhabits: He restrains a girlfriend by turning her arm behind her back and terrifies the girl. He threatens Rhiannon's friend Nathan with a knife and strikes Nathan with a baseball bat, injuring the boy's knee. These violent incidents are all part of the struggle between good and evil that pervades the novel.

Teen couples kiss. X says that he wants to be an object of "carnal attention," and other characters make references to sex, but there are no graphic sex scenes in this third book.

Profanity is used by unkind characters -- not so much by the likable main characters such as Rhiannon, A, and Nathan. Curse words and variations that appear once or twice each are "dumbass" and "dumbassery," "pissed," "f--k," and "f--kery."

Parents need to know that David Levithan's Someday is the author's third novel about real-life high school girl Rhiannon and the character called A, who wakes every morning in the body of a different teen. As in the previous books, Every Day and Another Day, the nature of this premise raises -- or rather erases -- questions about the importance of gender identity, sexual orientation, and physical appearance. Likewise, race, class, and nationality are rendered almost meaningless. What matters is the love between individuals who support and understand each other. This novel includes a little profanity (including "f--k" once or twice), teens kissing, and a couple of references to sex, though there's no graphic sexual activity in the book. There's some violence: A teen boy is bullied and beaten badly, and another boy is threatened with a knife and later struck in the knee with a baseball bat. The bodiless character X brags about his power to commit murder. One character is told he was possessed by the devil, and though readers know this is false, the power struggle between good and bad in the world of the novel may read like a struggle for the boy's soul.
