"Dublin, 1956: When Mary Kate Ryan loses the love of her life, she's not sure how she can keep going. Feeling completely lost, she allows her friend Moira Kent to persuade her to re-open the Boarding House for Single Ladies where she made so many memories and created a safe place for women in need. Now it's Mary Kate who needs to start over. As Mary Kate sits by the large bay window, with her little dog Guinness by her feet, she realizes there are others who need her help. Can Mary Kate and Moira uncover the mystery surrounding their new guest? And can they provide a home for two orphan sisters? Soon Mary Kate breathes new life into the boarding house and learns that family can be formed in all sorts of ways. Clever, kind Moira is like the sister she never had and Moira's sweet, adopted ten-year-old daughter Abby means the world to both of them. And being back in Merrion Square brings Mary Kate the laughter and joy that she never dreamed she'd experience again. But when a devastating secret about Abby's birth mother begins to unravel, it threatens to destroy the happiness of her patchwork family. Mary Kate must gather her strength to protect the future of the boarding house, and to stop darling Abby being taken from them."--Provided by publisher.
