Sergeant Preston of the Yukon #29

In "Forbidden Trails," a sudden ambush on the Yukon River leaves a steamer stripped of its precious cargo—bullion, gold dust, and cash—stolen by unseen river pirates who vanish without a trace. With no trail to follow and time running short, the search for the thieves begins in the frozen wilderness, where every shadow could hide a secret.

When Jo’s son goes missing in the frozen hills, Trader Storey—usually wary of the outlaw Chuck-A-Chuck—finds himself relying on the man’s rugged knowledge of the wild. As snow blankets the trails and time runs short, an unlikely alliance forms between a fearful man and a man with a past.
