Summer Affair by Jill Sanders

Two hearts, one summer:
can a playful summer affair
turn into forever love?
Dean is River Camps’ very own gigolo, or so the rumors have gone since the upscale, adults-only summer camp opened a few years ago. In reality, Dean was raised by a single mother and helped to bring up his younger sister, and he’s always respected women too much to be too big of a player. However, falling in love seemed totally out of the question for a guy like him. But when a close friend suggests a summer-only physical affair, he decides to dive in, especially since he already lost his heart to her years before.
Andrea is a free spirit who has sworn off permanent commitments. She believes in spreading love to all who are deserving, and Dean fits the bill. But her past has made her wary of letting anyone get too close. What started as a spontaneous decision for some summer fun has somehow grown into something deeper, making Andrea reconsider her stance on love and the possibility of opening her heart once more.
