Chained, muzzled, and caged, Nathan fights for his survival while struggling to contain the monster hiding inside him. But when the repeated beatings aren't enough to break him, the FIB calls in Shane Carlton, a professional torturer, with one goal: break Nathan so he reveals the location of his sister and boyfriend. His only hope is Birdie, someone he used to trust, but if Birdie can't act quickly to stop Shane then the monster hiding under Nathan's skin may endanger everyone they know.
