The Fall of Crazy House (Crazy House Series 2) by James Patterson

The best series since The Hunger Games just got better- Escape is just the beginning in this dystopian story of two fearless sisters who must defeat a powerful regime - or risk becoming what they despise. Twin sisters Becca and Cassie barely got out of the Crazy House alive. Now they're trained, skilled fighters who fear nothing - not even the all-powerful United regime. Together, the sisters hold the key to defeating the despotic government and freeing the people of the former United States. But to win this war, will the girls have to become the very thing they hate? In this gripping sequel to James Patterson's New York Times bestselling Ya (Young Adult) blockbuster Crazy House, the world is about to get even crazier.
