A pit of corpses. An ancient cult. A quest for redemption that could leave her dead…

New Mexico, 1952. Archaeology grad student Ruby Delgado is plagued by guilt after losing her son. So when her latest excavation drops her down a sinkhole filled with suspiciously mutilated bodies, she’s driven to bring the murderer to justice. But when digging deeper brings her dangerously close to a sinister religious sect, she could be their next sacrifice…

Discovering some of the victims were crucified, Ruby pushes hard to give the evidence to the authorities. But when her trail crosses the path of a beaten man left for dead in the desert, she realizes she may be the only person who can save the community.

Can Ruby stop the sacrifices and slay her inner demons, or will hers be the next body laid to rest?
