When Elizabeth receives her freshman-year roommate assignment at the beginning of summer, she shoots off an email to coordinate the basics: TV, microwave, mini-fridge. She can't wait to escape her New Jersey beach town, and her mom, and start life over in California. The first note to Lauren in San Francisco comes as a surprise; she had requested a single. But if Lauren's learned anything from being the oldest of six, it's that you can't always get what you want, especially when what you want is privacy. Soon the girls are emailing back and forth, sharing secrets even though they've never met. With family relationships and childhood friendships strained by change, it suddenly seems that the only people Elizabeth and Lauren can rely on are the complicated new boys in their lives ... and each other.
