Nothing ruins a lazy summer afternoon faster than the screams of a young girl. Liam Michaels, an earthbound archangel, and his partner Dani Suskin, an angelic warrior, see their day go to hell in a handbasket when they stumble on a sex trafficking ring. The day continues to spiral downward when the head of one of the captured traffickers explodes during questioning, a sure sign that the evil behind this ring is not human, and as Liam and Dani follow its trail through Rome, Bangkok, Mumbai, and Katmandu, they discover a deadly enemy unlike any they have ever faced. But Liam faces an even greater enemy-himself. As they plunge deeper into the heinous world of slavery and human exploitation controlled by a global crime organization, death touches the lives of his friends, and Liam must fight a two-front battle as he walks the fine line of a fall from grace.
