Book Summary[]
The Carlyles go on vacation to The Bahamas with Remington, their mom's fiancé, his daughter, Layla, and her boyfriend, Riley. They are joined by Rhys, Owen's friend, and Jack. Baby feels alone, until she realizes that she and Riley have a real connection. But she and Layla make a great team too... Rhys is being pressured by Hugh and the swim team to hook up with a girl, so Owen decides to set him up with an aggressive British girl. But the only girl Rhys has eyes for is Avery... Owen's sister. Jack realizes that her feelings for Owen run much deeper than she thought, but she can't bring herself to tell Avery. Amidst all of the secret drama, Remington and Edie Carlyle decide to get married. The sun isn't the only thing that's sizzling on this vacation getaway -- I'm forecasting sultry poolside encounters, too. So, don't forget to pack the sunscreen ... you don't want to get burned.
