This sequel to New York Times bestselling novel Extinction is a twisty supernatural-themed thriller full of gripping twists, perfect for fans of Michael Crichton and Scott Mariani.

A holy relic brutally defaced. A series of grisly murders. A secret that could change the world.

When a holy relic is defaced and a reclusive old prospector horribly murdered, Colorado Bureau of Investigation Agent Frankie Cash and Eagle County Sheriff Jim Colcord team up on their most enigmatic and dangerous case yet.

The murder is followed by the equally horrendous killing of a controversial scientist, tortured using medieval methods. The investigation uncovers further bizarre killings, a baffling money trail, and a fanatical secret society. But the key to everything is an alien artefact UFO researchers believe will change the world...

Meanwhile, the resurrected Neanderthals who vanished into the Colorado mountains during Cash and Colcord's last case are planning something that can only spell disaster for any nearby Homo sapiens.
