The Summer Girl

＂Claire’s younger sister Holly has been working on the millionaire’s playground of Martha’s Vineyard for the summer--all barefoot beach parties and flirting with the local rich kids. But now Holly is missing, and none of the locals seem to care, including the police. They think a message Claire received is proof she’s safe. But Claire knows that’s impossible. What will she have to risk to find out the truth? Who are the locals protecting? And what does it have to do with another girl who went missing five years ago?＂--
