As Evelyn becomes the perfect gentleman, Morgan becomes the perfect captain. It is down to Morgan to take command, down to Evelyn to hold fast, and down to both to navigate their own treacherous sea. Thirteen years ago, Evelyn Winthrop fled England to go a-whaling. But now that his father is dead, Evelyn must become a proper baronet to save the estate from his wastrel brother. He grudgingly accepts help from estate agent Morgan Turner, who is eager to carry out the late baronet's wishes. While repressed Morgan teaches rough-edged Evelyn to fit into high society, Evelyn seduces his closeted agent into embracing his true nature. Just when it all seems like smooth sailing, a mutual acquaintance returns make waves. Painful secrets from Morgan's past threaten his relationship—and the entire Winthrop estate along with it. In the midst of dysfunction, drama, and duels, Morgan must learn to trust again and disclose his harrowing past. Otherwise, Evelyn may abandon the estate and follow the siren song back to the sea.
