Entered into a wager that he can wed within a week, Captain Alex Bancroft pursues the first pretty woman he meets: Miss Emma Washer. Their courtship proceeds at a furious pace, including a dalliance that might ruin them both. Before it can, Alex proposes and is stunned when Emma agrees to marry him. Alex desperately tries to keep word of the wager from his new wife, not knowing Emma has secrets of her own to keep.
As passion erupts between the newly wed pair, the circumstances of Emma’s past threaten to tear them asunder. Alex’s regiment is directed to sail to a place Emma dares not go.

She refuses to accompany him, leaving Alex with a devastating choice: leave England to fulfill duty to Queen and country or stay and revel in his newfound love for his wife?
