There is a world parallel to our own in which the souls of the damned are caged, where they are looked over by the Furies, and where they spend eternity in torment, mirroring the mayhem they created when alive. Someone has opened the cage. The worst of terrors has crossed the barrier that separates our world from theirs, and the Furies send an untested warrior, their only son, Alek to try to bring those souls back. He is young, headstrong and impulsive, and he won't be able to do it alone. Eva has grown up beloved, but surrounded by secrets. First, she will be hunted in an ancient feud that will threaten her life. Then, she will become the hunter. With the police closing in and two worlds on the verge of crumbling around them, Alek and Eva must find each other, discover the limits of their powers, and work together to save everything they hold dear.
