A warrior angel breaks a Celestial Edict, thinking it's the right thing to do. He's caught, exiled to Earth, and placed in the body of an ordinary man where he must stay until there are no more humans. Existing rather than living, plotting revenge, and running a bookstore, this is how his story might have ended, but one blustery day a beguiling young woman, packing supernatural firepower, waltzes into his store and talks him into a hunt across twin universes in search of an unhinged archdemon of wrath, a demon who in legend destroys mundane reality.
Asariel (aka Kenrick Orson Fellian) has a choice: revenge, or a slim chance at saving the world. Guardian in Exile: The God Eater's Hellion is an urban fantasy with an epic journey and a dash of snark.
