A Danger to Herself and Others By Alyssa B. Sheinmel

Only when she’s locked away does the truth begin to escape…

Four walls. One window. No way to escape. Hannah knows there's been a mistake. She didn't need to be institutionalized. What happened to her roommate at her summer program was an accident. As soon as the doctors and judge figure out that she isn't a danger to herself or others, she can go home to start her senior year. In the meantime, she is going to use her persuasive skills to get the staff on her side.

Then Lucy arrives. Lucy has her own baggage. And she may be the only person who can get Hannah to confront the dangerous games and secrets that landed her in confinement in the first place.
