He'll protect his best friend's baby sister from anything...other than himself. 

Rhyland Coltridge is a hedonistic playboy, but he isn't stupid. He knows Dylan Casablancas is a forbidden fruit. She's his best friend's baby sister, a single mom, and a royal pain in his ass. All three make her entirely off-limits, which is just as well, as he doesn't do relationships. 

Unfortunately for him, she's moving into the apartment downstairs, and Rhyland's potential business partner, Bruce--an old-fashioned family guy with a Texan drawl--mistakes them for a couple. Rhyland wants Bruce's money. Dylan needs a big, burly guy to scare off her loser ex. On paper, pretending to be engaged would help them kill two birds with one stone. But in practice? Rhyland wonders if the sassy single mother just might be the death of him. The deal says their fake engagement ends as soon as Rhyland's contract is signed, but Rhyland took a bite of the forbidden fruit, and guess what? He isn't about to leave any crumbs for another man behind...
