Life, as Séamus Kierney knows it, is over. When the famous Irish singer and guitar guru of Kilts finds himself suddenly single dad to a biscuit-stealing wee monster named Róisín, all he knows is that his carefree days are over. In just a few short days, Séamus' new daughter gifts him with an explosive nappy, climbs the bookshelf with Séamus' music awards, and locks him out of the house--in his underwear. He handles all this with reasonably good grace, but when he's offered the road trip of a lifetime, and his good buddies are unable to mind the baby, he finds himself in desperate need of help. Good thing his nerdy neighbor is so easy to manipulate. Rebecca Foster, a PhD candidate studying at Dublin University, is no pushover. She knows what Séamus is doing--and she's got a few tricks of her own up her sleeve. Securing a promise from him to participate in her experiment at the local church, in exchange for her help, is just the beginning. Now if she could just keep her hands off the guy... Once in Séamus' house in Bray, and despite all of Rebecca's attempts to quell the attraction building between them, the two grown-ups in Róisín's life get cozy. Add in the "dog" Rebecca adopted without asking, and pressure from her parents, and life gets crazy. But Rebecca starts her new job at Yale in a few months. And then the only man that could put a monkeywrench in Séamus' deepening love for his daughter shows up. Can Séamus find a solution to keep his new little family together? Or is he doomed to revert back to his single life, now that he's finally fallen in love?
