A Coast Guard mission goes wrong, and a vengeful arms dealer targets rescue swimmer Neve Michaels and her family. Neve heads to South America to eliminate the threat, but her journey isn't without company: her self-appointed guardian, Russell "Rock" Kaczewski. The infuriatingly gorgeous ex-marine is the last man she wants…and the only one she needs.
Rock has worked hard to keep his mind, and hands, off his best friend's little sister, but keeping her safe from those who want her dead will put his code of conduct to the ultimate test. That stubborn woman is willing to do anything to save those she loves…and Rock will do everything to save Neve.
