Sandcastles: Star of the Sea Academy Series: Book 1 by Luanne Rice
Sculptor Honor Dillon has made a life for herself and her three daughters teaching art in the warm embrace of the Star of the Sea Academy, a thriving convent school blessed with a generous endowment, a beautiful seaside campus, and the enlightened stewardship of Mother Superior Bernadette Ignatius. The wedding of her oldest girl, Regis, should be an event of pure joy. But Regis' happiness will not be complete without her father, John, a brilliant, haunted photographer who broke Honor's heart. Now, after years spent in an Irish prison, John is coming back to the family he loved desperately and left behind, setting in motion a chain of events that will shake the old school to its foundations.
