"Agatha is pregnant and works part-time stocking shelves at a grocery store in a ritzy London suburb, counting down the days until her baby is due. As the hours of her shifts creep by in increasing discomfort, the one thing she looks forward to at work is catching a glimpse of Meghan, the effortlessly chic customer whose elegant lifestyle dazzles her. Meghan has it all: two perfect children, a handsome husband, a happy marriage, a stylish group of friends, and she writes perfectly droll confessional posts on her popular parenting blog--posts that Agatha reads with devotion each night as she waits for her absent boyfriend, the father of her baby, to maybe return her calls. When Agatha learns that Meghan is pregnant again, and that their due dates fall within the same month, she finally musters up the courage to speak to her, thrilled that they now have the ordeal of childbearing in common. Little does Meghan know that the mundane exchange she has with a grocery store employee during a hurried afternoon shopping trip is about to change the course of her not-so-perfect life forever."--
