Everything they ever thought about the Fallen was wrong.

Sadie Sloan is the only human in her circle of friends. And that’s the way she likes it. But when her little sister goes missing, Sadie is taken deep into the world of Guardians. With her friends distracted, she has no one but rogue Guardian (and biggest jerk), Sebastian, to help her. As they search, she discovers the Fallen have returned… and Sadie’s next on their list.

Leila and the clan drop everything to protect her, hiding in the woods from the rest of the world. But when Sadie gets Marked it becomes painfully clear—one of them is responsible.

Friendship is a dangerous game when someone you trust is after blood.
