When an angel and a demon fall in love, there's Hell to pay.... And Heaven's waiting its turn. Rome in the 10th century is full of demons and succubi, trying to influence and corrupt the church. To combat them are a host of angels and guardians. Kalili is a demon. Faith is an angel. When Faith encounters Kalili, sparks fly. It's impossible, but they can't deny their feelings. When they learn who—and what—they truly are? Neither side wants that. Both Heaven and Hell turn against the pair. All they can depend on is each other.
