A secret order of sorcerers rules the world. One man has vowed to destroy them.
It's their world. He's going to take it away from them.
The Apkallu are masters of magic. Theirs is a secret tradition stretching back to the dawn of civilization.

Under a new identity, Sam learns the secrets of magic, infiltrates the Apkallu, and walks a razor's edge as he picks off their leaders while avoiding supernatural detectives on his trail.
But Sam faces a greater threat: As he fights monsters, what is he becoming?
