Sam is seventeen, starving herself and longing for oblivion. Her sister, Jena, is mentally scarred and desperate to remember. Between them, they share secrets too terrible to recall.

Eighteen months earlier, Sam was still full of hope: hope that she could piece together Jena's fragmented memory after the vicious attack that changed their family forever. But digging into the past unearthed long-hidden lies and betrayals, and left Sam feeling helpless and alone in a world designed to deceive her.

Now, in a last bid to save her from self-imposed shutdown, Sam's therapist is helping her confront her memories. But the road to recovery is a dangerous one. Because Sam has not only been lying to her doctors: she's been hiding dark secrets from herself.
