Swapping Lives — Jane Green

What if a successful, single Londoner and a comfortable, Connecticut mother of two were to walk in each other's shoes for a month? Vicky Townsley is the director of Poise! magazine and lives a glamorous London life. She has everything she wants -- except marriage, children, and a house in the country. Amber Winslow has a stone mansion in Connecticut, two kids, and a nanny, but she hasn't found the fulfillment she had expected from being a wife and mother. When she spots an intriguing contest in Poise! Amber impulsively enters, never expecting to be picked.

A must-read for every modern woman who's ever considered the road not taken, Swapping Lives is a warm and realistic chronicle of two women who do more than wonder if the grass is greener on the other side of the Atlantic.
