Lord of the Sea — Em Petrova

When Aria Croft finally shed her mourning gloves, disguised herself as a boy, and joined the crew of the Lady's Grace, she thought she was just escaping her family situation. Once aboard, her identity is revealed by the dastardly pirate Bastian the Bastard and she's threatened by forty irate crewmen. But discovering the boy she once knew in the pirate's leather boots pushes aside her fear of being thrown overboard by superstitious pirates. Under Bastian's protection, she finds her body responds to him in all ways, even as her mind continues to rebel.

Sebastian Du Loc, more widely known as one of the hardest pirates on the sea, is stunned to find a curvaceous vixen aboard his ship. Not just any woman, but the sister of his late best friend. To keep her luscious body out of the hands of the rough crew, Sebastian proposes she become his mistress for six, lust-filled weeks. But when they finally reach land, will he be able to give her up or will his possessive nature rule?
