First-time author McGarry introduces two teenagers struggling to regain normalcy after their lives have been shattered by separate tragedies. No one knows what happened the night Echo Emerson went from popular girl to outsider with scars on her arms. Even Echo can't remember the whole truth of that horrible night. But when Noah Hutchins, the girl-using loner explodes into her life, Echo's world shifts in ways she could never have imagined. She has to ask herself just how far they can push the limits and what she'll risk for the one guy who might teach her how to love again.
