Tears of the Moon by Nora Roberts (Gallaghers of Ardmore #2)

Talented songwriter Shawn Gallagher works as the cook in the family pub. With no responsibilities and no ties, Shawn seems happy with his life.
No one understands why he doesn't put his musical gifts to profitable use - least of all Brenna O'Toole. Tough and independent, Brenna has also been secretly in love with Shawn for years. When she finally admits her true feelings, Shawn rejects her advances, protective of his single life. But Brenna doesn't give up that easily. And there are other forces at work in the enchanting village of Ardmore. Perhaps fate will step in with a helping hand...
