The Next Always by Nora Roberts. Book One of The Inn BoonsBoro Trilogy,

Meet the Montgomery brothers - Beckett, Ryder, and Owen - as they bring an intimate Bed-and-Breakfast to life, in their hometown. The historic hotel in Boonsboro, Maryland, has endured war and peace, the changing of hands, and even rumored hauntings. Now it's getting a major face lift from the Montgomery brothers and their eccentric mother. As the architect of the family, Beckett's social life consists mostly of talking shop over pizza and beer. But there's another project he's got his eye on: the girl he's been waiting to kiss since he was sixteen... After losing her husband and returning to her hometown, Clare Brewster soon settles into her life as the mother of three young sons while running the town's bookstore. Though busy and with little time for romance, Clare is drawn across the street by Beckett's transformation of the old inn, wanting to take a closer look ... at both the building and the man behind it. With the grand opening inching closer, Beckett is happy to give Clare a private tour -- one room at a time, in between blueprint meetings and kindergarten pickups. It's no first date, but these stolen moments are the beginning of something that could arouse the secret yearning that resides in Clare's independent heart -- and open the door to the extraordinary adventure of what comes next
