The kingdom
(Book)

Sequel to: Lost empire.

Treasure hunters Sam and Remi Fargo are asked by an oil baron to find his missing father--and their investigator friend who has also disappeared while looking for the man. 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, a balloon aircraft from a century before its time, 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.
