Lost Valley (Part 1: The Discovery)

Two boys have disappeared in the isolated mountains northeast of the remote Alaskan village of Manatuk, a forbidden region where ancient terrors are rumored to exist…and where local guides refuse to enter. Search and rescue specialist Luc Moon is tasked with the impossible: finding the boys on his own.

During the search, Luc discovers clues to a remarkable lost world, a world hidden deep within a forgotten valley. Now in a life-and-death struggle, Luc―and those closest to him―must survive against legendary creatures and a ruthless billionaire determined to keep the discovery to himself.
