The new powerhouse team of Douglas Preston & Aletheia Preston are joining together to "enter the world" of the New York Times bestselling Extinction.

One of the holiest relics in Christendom, inexplicably defaced…

A paranoid old prospector, ritualistically murdered…

A controversial exobiologist, tortured and dismembered…

When a reclusive man is found dead under grisly circumstances in the Colorado wilderness, CBI Agent Frankie Cash and Eagle County Sheriff Jim Colcord, whom we met in the New York Times bestseller, Extinction, team up again on their most enigmatic and dangerous case yet. Their investigation uncovers a trail of bizarre killings, baffling money transfers, and a fanatical secret society.

And all the while, the resurrected Neanderthals, who vanished into the Colorado mountains, seem to be biding their time for something…spectacular.
