Ordered to hold an abandoned army post, John Dunbar found himself alone, beyond the edge of civilization. Thievery and survival soon forced him into the Indian camp, where he began a dangerous adventure that changed his life forever.

Set in 1863, the novel follows Lieutenant John Dunbar on a magical journey from the ravages of the Civil War to the far reaches of the imperiled American frontier, a frontier he naively wants to see "before it is gone".
