Life has never been better for Jamie Donovan. Always has been. And now that it's his turn to take charge of the family pub, he truly feels like everything in his life is just the way it's supposed to be. Or it was until an early morning knock on his door ended with a baby on his doorstep. The man who can normally charm his way out of any situation doesn't know the first thing about taking care of a baby and running a business. And so he turns to his siblings for help. And once they tell him their solution, he wishes he'd never asked for help. Fallon Murphy has always prided herself on being good with people. In all her life, she's only met one person she hasn't been able to get along with. Unfortunately, their parents are best friends, and avoiding him just wasn't a choice. When his sister calls stating an emergency, the last thing Fallon expects is to find an abandoned baby—one that belongs to Jamie. As much as she'd love nothing more than to see Jamie fail at something, she would never put an innocent child at risk. They're rivals. Sworn enemies. And now...roommates. Can one small baby help turn adversaries into lovers? Or maybe even...a family?
