Grea Perrim is a reaper of souls, and it's her duty to bring the deceased to the other side. But in the world of reapers, death isn't any kind of equalizer. The value of a soul is directly tied to the peculiarity of its death.
Grea's supernatural senses bring her to a Halloween house party with three costumed guests. She soon finds the most valuable kind of soul: the victim of a locked-room murder.
In order to reap the soul, Grea must unravel the identity of its killer and explain its death in full.
Is this the work of a human? A witch? Or something else entirely...?
