The Favorite Daughter by Patti Callahan Henry

Ten years ago, Lena Donohue experienced a wedding-day betrayal so painful that she fled the small town of Watersend, South Carolina, and reinvented herself in New York City. Though now a freelance travel writer, the one place she rarely goes is home–until she learns of her dad’s failing health.

Returning to Watersend means seeing the sister she has avoided for a decade and the brother who runs the family’s Irish pub and has borne the burden of his sisters’ rift. While Alzheimer’s slowly steals their father’s memories, the siblings rush to preserve his life in stories and in photographs. As his secret past brings Lena’s own childhood into focus, it sends her on a journey to discover the true meaning of home.
