When Casey Chargot and her aristocratic fiance Dursley Carrington arrive in Alaska, they expect to simply revel in the magnificant power of the scenery and to fish in the salmon-rich waters. But no one has warned them of the menace in what is still untamed territory. And their rugged American guide, whose lifeblood is made up of the mountains and rivers of his adopted country, awakens within Casey an awareness of her own ancestry - and a recognition of what she really desires.
Irrevocably, Casey realises that she can never be happy within the constrained world of the English upper classes and breaks away from Dursley. But in a world where only the strong survive they must face the danger - together . . .
