Judy Haite (named for her mother's used bike) was raised in Maine and settles in Florida working as a physical therapist. She meets Sam, a multimillionaire, on the train to Machu Picchu, soon marries him and is transplanted to the posh island town of Palm Beach. The book follows Judy's life on Sunshine Street and the few year-round residents there. Something's a little odd about Judy, but is she a murderer?
