Suspected of killing her husband, Charity Westcott flees on the first ship out of Portsmouth, England heading for the colonies. Loathing all men after her abusive marriage, she hopes to reunite with her family in Charles Towne, but the ship ends up in Nassau. When she spots her husband's brother, who is intent on seeing her hang, boarding her ship, she jumps overboard.

Elias Dutton, missionary and son of the famous pirate, Rowan Dutton, must get to Barbados as soon as possible. His sister is in danger, and his parents have charged him with her safety. He cannot let them down again. But after rescuing a madcap woman from the bay, he now finds himself tricked into masquerading as her husband so they both can procure passage to Barbados.

Pirates, storms, shipwreck and betrayal threaten to delay the couple in their journey even as sparks fly between them. With her brother-in-law in fast pursuit, the last thing Charity wants is help from a man, especially a religious one, but she has no choice. After Elias' heart was broken by a sordid woman who nearly ruined his life, he seeks a godly woman pure as the virgin sands of the Caribbean. He believes he has found such a woman in Charity. Until he discovers she is a murderer and is now faced with two choices: letting her go or turning her in to the authorities.
