Temporary Dad by Dev Bentham

Nick Compton owns a small but mighty fashion magazine. He already has enough on his plate, between work and, well, work. There’s no room for a kid in his life but when his sister drops her seven-year-old daughter for an extended stay, he has to figure it out. Just before his niece arrives, Nick meets a blazing hot firefighter. They get on like a house a fire and the sex—scorching. Too bad the he disappeared in the morning. Like smoke. Now Nick’s stuck with a kid he doesn’t know how to manage and without the man he’d love to get his hands on again.
Dylan Gil wishes like hell he hadn’t taken his roommates advice and lied about who he was. He’s finally met someone he really likes and can’t stop thinking about. But now he’s too embarrassed to confess that he’s just a second-grade teacher, not a manly firefighter. Good thing that work gets distracting, particularly when one of his brightest students goes to stay with her uncle and all hell breaks loose. Some people shouldn’t be allowed to have kids.
If the term “dad pants” means anything it’s that taking care of children and fashion aren’t compatible. Does that mean these two doomed? Or is this the beginning of forever?
