When Brea Tackett is gunned down in cold blood her guardian angel is unable to leave her to face an eternity in hell. Nox knows Angels aren't supposed to fall in love, but that rule was broken with Brea long ago. So he strikes a deal with Azrael, the Angel of Death, for the future of her soul.

Becoming a Reaper allows Brea a chance at redemption. Purgatory is a world unlike any she's ever dreamed of—filled with Angels, Demons, and temptation. But with training and the desire to succeed, she's walking the straight and narrow, with one exception—Nox.
