Three-year-old Wren is a probationary Reaper sent on her first solo mission: collect four overdue souls living under one roof—a vampire named Margo, a werewolf named Kane, a witch named Vera, and a one-winged fairy named Feli.
It should be a simple assignment. But when Wren raises her scythe, Margo catches her instead of letting her fall. Kane protects her even when she comes to collect his soul. Vera teaches her that making mistakes does not mean being abandoned. And Feli shows her something Reaper training never taught her—how to play.
The longer Wren stays with this strange monster family, the less she can complete her job. Breaking the rules, she begins returning their souls to their bodies, but every life she saves burns away part of her own existence.
When the Department sends Eraser, an unstoppable final executor, to finish the mission, Wren discovers a secret from 300 years ago: she was once the child Margo failed to save from death.
But before they knew they shared a past, they had already chosen each other.
Now Wren must decide: remain the Reaper she was created to be, or give up everything she has to keep the family she finally found.
