You Against Me — Jenny Downham

If someone hurts your sister and you're any kind of man, you seek revenge.
If your brother's accused of a terrible crime but says he didn't do it, you defend him.

When Mikey's sister claims a boy assaulted her, his world begins to fall apart. When Ellie's brother is charged with the offense, her world begins to unravel. When Mikey and Ellie meet, two worlds collide.

This is a brave and unflinching novel from the bestselling author of Before I Die. It's a book about loyalty and the choices that come with it. But above all, it's a book about love.
