Abbott, Hailey. Summer Boys.
I am a little late to the party as far as getting into this series. I had heard of it, but never bothered to try reading them. The series follows a group of cousins and friends each summer at their summer cottages in Maine. The story lines all seem to follow the romantic lives of the girls and guys and nothing else. So, while the books are interesting in the soap-opera sort of way that keeps you coming back for more, there isn't anything else going on aside from crushes, dating, and sex. I would recommend the series for fans of series fiction.
