The husband-and-wife team of Sam and Remi Fargo are used to hunting for treasure, but they aren’t used to hunting for people—until an investigator friend of their goes missing, and they promise to search for him. What they discover, however, will be beyond anything they could have imagined.

On a journey that will take them to Tibet, Nepal, China, Italy, and Siberia, the Fargos find themselves embroiled with black-market fossils, an ancient Tibetan kingdom, a lost landmass in the North Sea, Stone Age ostrich egg shards inscribed in a cryptic language, a pair of battles separated by thousands of miles and hundreds of years . . . And a skeleton that could just turn the history of human evolution on its head.
