Science fiction becomes reality in this Jurassic Park-like story of the genetic resurrection of an extinct species - the woolly mammoth - by the best-selling author of The Accidental Billionaires and The 37th Parallel.

"With his knack for turning narrative nonfiction into stories worthy of the best thriller fiction" (Omnivoracious), Ben Mezrich takes us on an exhilarating true adventure story from the icy terrain of Siberia to the cutting-edge genetic labs of Harvard University. A group of young scientists, under the guidance of Dr. George Church, the most brilliant geneticist of our time, works to make fantasy reality by sequencing the DNA of a frozen woolly mammoth harvested from above the Arctic Circle and splicing elements of that sequence into the DNA of a modern elephant. Will they be able to turn the hybrid cells into a functional embryo and bring the extinct creatures to life in our modern world?

Along with Church and his team of Harvard scientists, a world-famous conservationist and a genius Russian scientist plan to turn a tract of the Siberian tundra into Pleistocene Park, populating the permafrost with ancient herbivores as a hedge against an environmental ticking time bomb.

More than a story of genetics, this is a thriller illuminating the race against global warming, the incredible power of modern technology, the brave fossil hunters who battle polar bears and extreme weather conditions, and the ethical quandary of cloning extinct animals. Can we right the wrongs of our ancestors who hunted the woolly mammoth to extinction - and at what cost?
