When Scarlet finds herself doomed to eternal punishment in Hell for a sinful life she can't even remember, Satan himself offers her a deal: return to earth and kill one marked sinner per day...as his grim reaper!

Using the power of Hell, Scarlet quickly learns the ropes of being a reaper: bring in one sinner per day, regardless of their sins, and avoid the ninth circle herself. This work brings her into the path of Chase, a disgraced former detective trying to solve a high-level case that seems wrapped up in Scarlet's former life. Scarlet decides to partner with Chase to find the answers to her locked memories--as long as Chase doesn't discover Scarlet's bloodstained bargain with Satan first.
