An epic thriller from #1 New York Times bestselling author Douglas Preston, perfect for fans of Michael Crichton. Extinction explores the very real effort to resurrect the woolly mammoth and other extinct megafauna from the Pleistocene Age. Erebus Resort, occupying a magnificent hundred-thousand acre valley deep in the Colorado Rockies, offers guests the experience of viewing woolly mammoths, Irish Elk, and giant ground sloths in their native habitat, brought back from extinction through the magic of genetic manipulation. When a billionaire's son and his new wife are kidnapped and murdered in the Erebus back country by what is assumed to be a gang of eco-terrorists, Colorado Bureau of Investigation Agent Frances Cash partners with county sheriff James Colcord to track down the perpetrators. As killings mount and the valley is evacuated, Cash and Colcord must confront an ancient, intelligent, and malevolent presence at Erebus, bent not on resurrection... but extinction. 'A thriller as breathlessly riveting as you would expect from a genre master like Douglas Preston, but much more too: it's meaty and thought-provoking, and tells us a lot about our distant past - and our immediate future. Spectacular!' Lee Child
