Fans of The Holiday, this one's for you. Green's Swapping Lives finds a Connecticut wife and mother and a London magazine editor trading places for one month. Each of them is just dissatisfied enough with their own existences to try someone else's on for size. Despite both of them having lovely lives, going along with them as they immerse themselves in new environments proves to be a fun and occasionally poignant take on the old grass is always greener adage. This is the author at her frothy best; the stakes are relatively low, but the characters and their journeys (and the loving description of a gorgeous Connecticut home) make this book a pleasant, breezy read.
