My Fair Lover by Nicole Jordan

Lady Katherine Wilde believes she has crushed any lingering romantic feelings toward Brandon Deverill, who spurned her six years ago. And now that the rough-edged rogue needs polishing to claim his inheritance, she’s willing to strike a practical bargain: Kate will mold the brash privateer into an acceptable English nobleman if Deverill will safeguard her from brigands on a voyage to recover lost family treasure. However, the soul-melting kiss that seals their agreement just may reignite blazing passion.

Brandon’s fortitude was sorely tested when he turned Kate away from his bed all those years ago. Even a rake such as he wouldn’t seduce an innocent beauty before sailing into battle. But now that he’s inherited a title and must take a suitable bride, he sets his sights on Kate. Though he fiercely desires her, true love is a notion that baffles him–until their adventure turns perilous and Brandon realizes he’d gladly trade his life to save the woman who has captured his heart.
