Demo's life is full of uncertainties. As the Gatekeeper of Heaven's son, one would think he had it easy. Being half demon complicates things, making him hated and feared instead. Hera herself is surprised when Fate steps in to make him part of an elite team of Angelic Guardians. Joined by a gorgeous Goddess, a shy Atlantean, and a monk with anger issues, Demo must protect the World from a Demigod obsessed with Star Trek, not to mention revenge.
