A nameless reaper finds the last living human and harvests his soul for her master, expecting the reward he promised—freedom. But Lucifer is a clever master, one who isn't ready to let a subject regain free will easily. The reaper's only hope is to find the angel who witnessed the harvesting and convince him to testify on her behalf. Without proof, she is at the mercy of Lucifer, and at risk of spending eternity in the depths of her own personal hell.
