The Hotel Nantucket by Elin Hilderbrand

 London billionaire Xavier Darling decides to resurrect the long-neglected Hotel Nantucket and turn it into a destination spot on the island--though no one can figure out why, since he's never been to Nantucket. Lizbet Keaton, fresh from a breakup with her long-time boyfriend and business partner JJ, talks her way into the position of general manager. Xavier insists that the hotel must get a heretofore unattainable 5-key review from the elusive but influential hotel critic and blogger Shelley Carpenter. 

We meet the cast of characters working at the hotel: Edie, Alessandra, Zeke, Adam, Magda, Mario, Richie--and learn all of their stories. We also meet Grace, the ghost of a young maid who was murdered in the hotel in 1920. It's just the perfect summer read.
