Cendall, history's first female Grim Reaper, has until her eighteenth birthday to prove she's worthy of the role. The only obstacle in her way are those pesky Guardian Angels who protect human souls, but Cendall is certain she can handle any Guardian who gets in her way. However, nothing could have prepared Cendall for Lacie-a soul that is protected by multiple Guardians, wanted by Demons, and, most startling of all, can see Cendall. Cendall uses every trick in the book to try and slip past Lacie's Guardians and collect her soul, but a Demon interferes at the last moment. In the chaos, Cendall accidently saves Lacie's soul, along with one of the injured Guardians. Realizing Cendall fears termination for her mistake, the Guardian blackmails her with an offer she can't refuse: in exchange for his silence, Cendall must keep Lacie's soul safe from the Demon, until he recovers from his injuries. Cendall agrees-with the intention of checking Lacie's soul off her list, the instant the Guardian is healed. But as the three of them are forced to work together, Cendall begins to question why Lacie is wanted by the Demons and if her name actually belonged on Cendall's list in the first place.
