The CaptureBook - 2016
"Fourteen escaped and found their way to a new territory, but Book, Hope, and Cat can't settle into their new free life knowing the rest of the Less thanks and Sisters are still imprisoned. Now the Teens must retrace their steps to save the others and destroy the compound. But the path back is filled with even more heart-pounding danger--as motives are questioned and relationships tested"-- Provided by publisher.
