Rules are made to be broken . . . When it comes to dating, ex-Navy SEAL Marcus Denali has a few simple rules. Never date a coworker. Never date a friend's sister. And never ever date a girl whose brother is a coworker, a friend, and a fellow SEAL. So why would Marcus dance so closely—and flirt so shamelessly—with Mandy Lawson? Simple. It's a Fourth of July masquerade ball. He doesn't know she's his buddy's little sister. And once the masks come off, the real fireworks begin . . . Mandy doesn't care about the rules. She's been crushing on Marcus for years, and she's not giving up now that she has proof he wants her too. She has a plan to show this military man some moves he never learned in basic training. And Marcus is going to learn that some rules-the rules of attraction—are just too strong to fight.
