When the Grim Reaper vanishes, fifteen-year-old outcast Cass Wilder, the only living human with soul-sight, is forced into the role of death’s untested successor.

With only the sharp-tongued anomaly Elsa and a jittery archivist named Pip at his side, Cass must master a job he never wanted just as a grieving mother transforms into something powerful enough to tear death itself apart to get back to her children.
