Watch out world!
The Great Gilly Hopkins is looking for a home. She's a foster kid who's been angry, lonely, and hurting for so long that's she's always ready for a fight. Be on the lookout for her best barracuda smile, the one she saves for well-meaning social workers. Watch out for her most fearful look, a cross between Dracula and Godzilla, used especially to scare shy foster brothers. Don't be fooled by her "Who me?" expression, guaranteed to trick foster parents, teachers, and anyone who gets in her way.

It's Gilly Hopkins vs. the world! And so far, Gilly seems to be winning. But what she doesn't realize is that every time she wins, she really loses, until she discovers a love as formidable as any enemy she's ever known.
