Extinction: A Novel (Cash & Colcord Book 1)

Extinction by #1 New York Times bestselling author Douglas Preston is a fast-paced thriller in the style of Michael Crichton, exploring the potential dangers of de-extinction science.

At Erebus Resort, a vast sanctuary hidden in the Colorado Rockies, guests can witness woolly mammoths, Irish elk, and giant ground sloths—species revived through genetic engineering. When a billionaire’s son and his wife are brutally murdered in the resort’s wilderness, investigators believe eco-terrorists are to blame. Colorado Bureau of Investigation Agent Frances Cash teams up with Sheriff James Colcord to uncover the truth.

But as more deaths occur and the valley is evacuated, they discover that something far older, smarter, and more sinister than humans is behind the violence—an ancient force not seeking resurrection, but total extinction.
