Looking for a light and breezy beach read for the end of summer? Claire Cook's "Time Flies"  takes the reader on a road trip on Cape Cod with Melanie and her best friend B.J. Melanie's husband Kurt has left her for a woman named Crissy, and she lets B.J. talk her into attending their high school reunion. It's been..umm..decades since they graduated. The reunion plans, which include a week at a classmate's beach cottage, don't quite turn out to be what Melanie signed up for. Cook is the author of "Must Love Dogs."
