Nyssa Summers is an ordinary nurse. However, since she began working on the coma ward, she is seeing things she shouldn't. Such as Thanatos, the god of death, who arrives to escort the souls of the dead to the afterlife. She's drawn to him, despite his macabre job, and they have established a bizarre sort of friendship. With the arrival of Thanatos's brother, Hypnos, Nyssa finds herself pitted between the siblings, reigniting a rivalry as old as time itself. After a killer begins to target the women at the hospital where Nyssa works, Thanatos offers to hide her from danger. As tempting as it is to spend some time in seclusion with him, even his realm isn't safe. Because the killer who wants her dead is a god, as well.
