Nineteen-year-old Kennet Singleton lives with his invalid mother in a personal care facility, but he wants out. He operates the crematory at the local funeral home, where he discovers he can discern the cause of death of those he cremates—by toasting marshmallows over their ashes.

He thinks his ability is no big deal since his customers are already dead. But when his perception differs from what’s on the death certificate, he finds himself in the midst of murderers. To save the residents and avenge the dead, he must bring the killers to justice.
