In Molly Shapiro’s fun and sexy debut novel, four women try to sort through the wild and complicated world of text messaging, status updates, and other high-speed connections.    Best friends and fellow midwesterners Katie, Annie, Maxine, and Claudia are no strangers to dealing with love and relationships, but with online dating and social networking now in the mix, they all have the feeling they’re not in Kansas anymore. Katie, a divorced mother of two, secretly seeks companionship through the Internet only to discover that the rules of the dating game have drastically changed. Annie, a high-powered East Coast transplant, longs for a baby, yet her online search for a sperm donor is not as easy—or anonymous—as she anticipates.
