Atia is a monster who feeds on fear. As the last of her kind, she hides in the shadows of the world to escape the wrath of the unpredictable Gods. Silas is a Herald, carrying messages and ferrying the dead as punishment for a past he can't remember. Stripped of his true name, he yearns to recover his identity.

Atia would never dream of allying with someone like him, but when she breaks a sacred law and the Gods send monsters to hunt her, Silas offers an irresistible deal: he'll help avenge her family and take on the Gods who now hunt her, if she helps him break his curse and restore his humanity. All they need to do is kill three powerful creatures: a vampire, a banshee, and one of the very Gods who destroyed both their lives. Only together can they finally rewrite their destinies.
