When twelve-year-old Miguel's gang member Papa makes promises to Santa Muerte, someone in Miguel's family loses a soul. The last time, it was Miguel's gentle aunt. This time, the target is Miguel's brother, Juan.
Santa Muerte, the skeletal patron saint of drug traffickers and murderers, always claims her fee.
The trouble is Miguel won't let Juan's spirit go. The resulting paranormal possession attracts demons, doppelgangers, and an ancient soul slayer from the depths of Hell - all of whom must be vanquished if Miguel is to live.
Even with help, Miguel's refusal to release Juan threatens the lives of those Miguel loves most. Miguel must choose to release his brother or lose yet another loved one, for the bargain was made with Santa Muerte and the price must be paid.
