Things are a little rough for Izzy Lane. Still reeling from the break-up of her marriage, the newly single mom moves back to the Philadelphia home she grew up in, five-year-old Noah in tow. The transition is difficult, but with the help of her best friends-and her elderly neighbor, Mrs. Feldman-Izzy feels like she's stepping closer to her new normal. Until her ex-husband shows up with his girlfriend. That's when Izzy invents a boyfriend of her own. And that's when life gets complicated. Blogging about her "new guy" provides Izzy with something to do when Noah's asleep. What's the harm in a few made-up stories? But when her friends want to meet the mysterious "Mac," someone online suspects Izzy's a fraud, and a guy in real life catches her eye, Izzy realizes just how high the stakes are.
