Vanessa wants just one thing for her twenty-ninth birthday: an engagement ring from her longtime boyfriend, Eric. But when the ring turns out to be a mix CD and Eric turns out to be a guy who doesn't want to get married or have children, Vanessa considers a new path to having a family.

When Wendy and her husband, Darren, couldn't have children the old- fashioned way, a sperm donor seemed like the perfect solution. She never imagined she'd have out-of-control twins who'd drive her to cookie binges and scrapbooking while Darren escaped into the virtual world of computer games.

Single and career-driven, Laura didn't need a man to have a baby - at least not one that she ever met. Thanks to an anonymous donor, she shares her life with her adored eight-year-old son, Ian. She'll do anything for Ian - even fill their backyard with a bunch of noisy chickens. But the one thing Ian really wants is something Laura's never been able to give him: a sibling.

Now, to grant Ian's wish, Laura starts a search that will not only change her life but Vanessa's and Wendy's as well...
