The year is 1945. Claire Randall is traveling with her husband when she touches a boulder in one of the ancient stone circles that dot the British Isles. Suddenly she is hurled back in time to a Scotland torn by war and raiding border clans in the year of our Lord 1743. Catapulted into the intrigues of lairds and spies that may threaten her life, she soon realizes that an alliance with James Fraser, a gallant young Scots warrior, might be the only way to survive. Thus begins a work of unrivaled storytelling that has become a modern classic.
