Kelli Barrack has spent the last three years imprisoned in Dr. Greenway’s facility plotting her escape, but when her chance comes one Halloween evening, it’s in a way she never expected.

Nate Halliway is being removed from the facility, but he refuses to go without his special forces team-mate, Giles. When his resistance lands him in Kelli’s cell, they both get a chance for freedom, a chance they take with both hands.

But as Giles, Nate and Kelli fight their way out, Kelli discovers that the most insidious danger to her freedom might lie within her, rather than in the small army out to stop them.
