Odinn’s Child (Viking #1)

In 1001, the young child, Thorgils Leiffson, son of Leif the Lucky and Thorgunna, arrives on the shores of Greenland to be brought up by a young woman--Gudrid. Thorgils is a rootless character of quicksilver intelligence and adaptability. He has inherited his mother's ability of second sight, and his mentors teach him the ancient ways and warn him of the invasion of the "White Christ" into the land of the "Old Gods." Guided by a restless quest for adventure and the wanderlust of his favored god, Odinn, Thorgils' fortunes will take him into worlds of unimaginable danger and discovery.
