Book excerpt: One house. Forty strangers. Add vodka and stir . . . Every summer, scores of Manhattan twentysomethings take part in an annual ritual with a camp-like culture distinctly its own: the Hamptons sharehouse. When Rachel and her two best friends buy their shares for twenty times each of their bank balances, they're imagining days filled with lazy suntanning and classy clambakes and nights spent rubbing shoulders with the Olsen twins and other celebrities. But once they arrive at 1088 Montauk Highway on Memorial Day weekend, they find that the reality falls a bit short. What looks like any other million-dollar mansion--on the outside--plays host to drunken escapades, explicit nudity, hot tub hookups, hideous hangovers, and juvenile mischief on the inside. As housemates jockey for limited bathroom time and beer pong mania takes over the house, Rachel finds herself wondering if it's possible to find true love--or even just survive the summer--in The Hamptons.
