Three dads. One nanny. Zero rules. I'm Grayson Ross-rich, handsome, successful. I always know what I'm doing, and I do it all well. Until her. My seven-month-old daughter I didn't even know existed. I need help. Thank god my neighbor's gorgeous friend steps off the elevator just as my nanny quits. Caroline is curvy, sassy, and between jobs-and she doesn't think I'm crazy when I beg her to step in. She's perfect. Not just because she's unfazed by the World's Grumpiest Baby, but because she's only in town temporarily. No strings. No risk. All I have to do is keep repeating: Don't f-k the nanny. Too bad she's already tangling the sheets with my neighbor and fellow dad, James-her high school ex-and his husband, the charming, nerdy Cas. Am I jealous? Maybe. But Caroline's clearly up for some dirty fun while she's here. And honestly, so am I. I'm not going to make her choose. I promise we give her a stay she won't forget-together. Soon, I'm back to feeling like my usual, in-control self. Until I mess it all by falling in love. With my daughter. This town. This life. And them. Sex is good and dirty. But love? That's where things get really messy.
