Island Summer Series by Jenny O'Connell

There are two kinds of people on the island -- those who leave at summer's end...and those who are left behind. Kendra and Mona are best friends, local girls who spend their summers catering to rich tourists and the rest of the year chafing against small-town life. Then Mona's mom marries one of the island's rich summer visitors, and Mona joins the world of the Boston elite, leaving Kendra and Martha's Vineyard behind. When Mona returns the following summer, everything is different... moreThere are two kinds of people on the island -- those who leave at summer's end...and those who are left behind. Kendra and Mona are best friends, local girls who spend their summers catering to rich tourists and the rest of the year chafing against small-town life. Then Mona's mom marries one of the island's rich summer visitors, and Mona joins the world of the Boston elite, leaving Kendra and Martha's Vineyard behind. When Mona returns the following summer, everything is different. Now Mona spends her days sunbathing with her private-school friends, while Kendra works at The Willow Inn -- a job she and Mona once hoped to do together. Unlike his sister, Mona's twin brother Henry hasn't changed. He's spending his summer the way he always has: with long, quiet hours fishing. Early mornings before work become special for Kendra as she starts sharing them with Henry, hoping he can help her figure Mona out. Then Kendra hatches a plan to prove she's Mona's one true friend. She'll uncover the identity of the twins' birth father, a question that has always obsessed Mona. And so she sets out to unravel the seventeen-year-old mystery of the summer boy who charmed Mona's mother. But are some secrets better off staying buried? less

For seventeen-year-old Winnie, summer can't arrive fast enough -- anything to get out of the house and escape the cold war brewing between her parents. With her older sister, Shelby, spending the summer in Boston, Winnie's left to deal with the situation all by herself. Which is why she's happy to spend all day away from home at a cushy job -- camp counselor at the prestigious Oceanview Inn. And when the Barclays, a wealthy summer family, offer Winnie an additional babysitting job in the evenings after work, she jumps at the opportunity. Little Cassie Barclay is fun to take care of, and hanging out in the gorgeous Barclay summer house overlooking the harbor is far more pleasant than being on the front lines of the battle between her parents. Then Cassie's older and devastatingly attractive stepbrother Jay arrives on the island after a disastrous first year at college, and he seems to want nothing more than to wreak havoc for his stepmother and the rest of his family. Winnie soon discovers that life in the Barclay summer house isn't so perfect after all, and what was supposed to be a carefree summer escapade is quickly becoming more complicated than she ever thought possible.... less
