Life is anything but perfect for Hallie Hartley, a young physical therapist who has given up nearly everything--even her love life--for her beautiful blonde stepsister, Shelly. Though Shelly's acting career has never taken off, she has certainly perfected the crocodile tears to get what she wants--which all too often means Hallie's boyfriends. When Hallie arrives home early from work one fateful day, she makes two startling discoveries that will turn her life upside down: Not only has a mysterious relative left Hallie a house on Nantucket, but Shelly has been trying to steal it. Desperate to put her troubles behind her, Hallie impulsively flies to Nantucket.
