Marshall Bowen is more comfortable sitting in a boardroom, but now he has his baby niece, Tessa, to take care of. Until very recently, Marshall didn't even know he had a sister, and the baby is a complete shock to him. He's out of his comfort zone and doesn't know the first thing about taking care of a baby. But he'll have to learn fast. He does have some help. Cody is his late sister's best friend, and he has become incredibly attached to the baby. After he and Cody meet, Marshall is determined to keep the young man around. It's only for Tessa's sake, of course. He would never indulge in his budding attraction to the baby's manny. Cody is glad to help Marshall take care of Tessa, but it's only a temporary arrangement. Once Marshall gets the hang of parenting, Cody will go back to his old life. He can't stay Tessa's manny forever, can he? But what will happen when Cody wants more? Will Marshall want a future with him?
