FBI agent John Sharpe was closing in on a criminal he'd made his life's mission to put away for life. So rescuing Sydney Westlake from the churning ocean was a distraction he couldn't afford. But then he learned the beautiful scientist had escaped his target's clutches and could hold the key to closing his case, so John wasn't letting her out of his sight. Sydney claimed she was more than willing to help, especially if it meant securing her twin sister's safety, but danger threatened every move she and John made together. Would the same hold true once their barely contained attraction was finally released?
