Royal Protector by Laura Gordon

Lexie Dale was a princess, the possible heir to a throne, and she'd come to the Garrett guest ranch for a much-needed retreat. But it was in Lucas Garrett's arms that she discovered true passion and a treasure beyond a king's ransom...

Lucas was a lawman and a cowboy, and his first priority was keeping Lexie safe. His second was keeping his heart safe from heartbreak, for Lexie was a woman without equal. And although he was more than a match for his headstrong princess, was he strong enough to protect her from a determined abductor?
