The Sunday Times bestseller, a Times Book of the Year, a Guardian Book of the Year, a Metro Book of the Year. At 14, Turtle Alveston knows the use of every gun on her wall; that chaos is coming and only the strong will survive it; that her daddy loves her more than anything else in this world. And he'll do whatever it takes to keep her with him. She doesn't know why she feels so different from the other girls at school; why the line between love and pain can be so hard to see; why making a friend may be the bravest and most terrifying thing she has ever done. And what her daddy will do when he finds out ... Sometimes strength is not the same as courage. Sometimes leaving is not the only way to escape. Sometimes surviving isn't enough.
