Kidnapped from his safe California home. Thrown into a life-death struggle in the frozen Arctic wilderness. Half St. Bernard, half Shepard, Buck learns many hard lessons as a sled dog: the lesson of the lash, of the cold, of near-starvation and cruelty. And the greatest lesson he learns from his last owner, John Thorton: the power of love and loyalty.
Yet always, even at the side of the human he loves, Buck feels the pull in his bones, an urge to answer his wolf ancestors as they howl to him...Can Buck resist the lure of the wolves?
