Broken for you / Stephanie Kallos.

Enhanced descriptions from Syndetics:

National best seller and Today show Book Club selection, Broken for You is the story of two women in self-imposed exile whose lives are transformed when their paths intersect. Stephanie Kallos's debut novel is a work of infinite charm, wit and heart. It is also a glorious homage to the beauty of broken things. When we meet septuagenarian Margaret Hughes, she is living alone in a mansion in Seattle with only a massive collection of valuable antiques for company. Enter Wanda Schultz, a young woman with a broken heart who has come west to search for her wayward boyfriend. Both women are guarding dark secrets and have spent many years building up protective armor against the outside world. As their tentative friendship evolves, the armor begins to fall away and Margaret opens her house to the younger woman. This launches a series of unanticipated events, leading Margaret to discover a way to redeem her cursed past, and Wanda to learn the true purpose of her cross-country journey. Both funny and heartbreaking, Broken for You is a testament to the saving graces of surrogate families and shows how far the tiniest repair jobs can go in righting the world's wrongs.
