How the Other Half Hamptons

Having authored a series of New York Post columns about her Hamptons McMansion summer share experiences, Rosemberg here follows friends Jamie, Rachel and Allison as they plunk down upwards of two grand apiece for the privilege of sharing a bedroom and jockeying for bathroom space on alternate weekends, and set out to find the men of their dreams or, in Jamie's case, passing fancies. Rachel hopes to duplicate too-perfect older sisiter Dana's huband-hunting success; Allison locates some mixed feelings for her previously uninspiring ex-; Jamie's not-too-friendly rivalry with flirtatious housemate Ilana colors her macking. First-time novelist Rosemberg has a sharp eye for telling details and an amusing way of limning the alcohol-soaked, sexually rampant funseeking crowd, but most of the characters blur together (especially the men), and the book never registers much emotional impact.
