Luca hates angels, hates the Underworld and hates being bossed around more than anything. When the ruler of the Underworld asks him to go find the Seer's heir in the human world, he knows it's only a question of time until he gets involved in some epic trouble. As he is dragged in a power game between Heaven and the Underworld, he might find the strength to mend a broken friendship, get over his troubled past, and even to defy the angels.
