The Wicked We Have Done (A Chaos Theory #1)by Sarah Harian  March 18th 2014 by Penguin/InterMix Books

 Evalyn Ibarra never expected to be an accused killer and experimental prison test subject. A year ago, she was a normal college student. Now she’s been sentenced to a month in the compass room—an advanced prison obstacle course designed by the government to execute justice.

If she survives, the world will know she’s innocent.

Locked up with nine notorious and potentially psychotic criminals, Evalyn must fight the prison and dismantle her past to stay alive. But the system prized for accuracy appears to be killing at random.

She doesn’t plan on making friends.

She doesn’t plan on falling in love, either.
