“Grand Isle,” Sarah Van Arsdale’s absorbing and suspenseful new novel, takes place in an eponymous North Fork enclave that closely resembles Shelter Island. A rather large cast of characters, most of them summer residents of Grand Isle, are introduced early on. It’s to Ms. Van Arsdale’s credit that they’re all clearly differentiated and pertinent to the tragedy at the heart of the story: an accidental death and its cover-up that create a ripple effect in the island’s close-knit community.
