A Best Friend's Little Sister Romance It seemed like a good idea at the time. A two-week Hawaiian vacation with a beautiful woman. What could go wrong? Well, when that woman is my best friend’s little sister, the answer is - everything. Mackenzie Langston has been in my life since we were kids, and until now, I didn’t see past her family and our friendship. So when she tells me she’s sworn off men for the next year after a bad breakup, I jump at the chance to have some company on the vacation I’d booked for me and my cheating ex. But Mack’s all grown up, and we’re both on the rebound. In a romantic suite with just one bed, the weather isn’t the only thing that gets hot.
