Decades after spending a summer in the Irish countryside with her parents-author Deborah Love and National Book Award winner Peter Matthiessen-Rue takes her young family back to Ireland to revisit locales from that season in the sixties. As a guide, she has her mother's poetic book, Annaghkeen, named for the castle that overlooked their home in Galway. What begins as a simple, nostalgic trip quickly becomes something far more complex. As Rue approaches Annaghkeen Castle and digs deeper into her parents' literary legacy, a trove of memories is unearthed, forcing her to reckon with a childhood fraught with the stormy energy of two brilliant parents often at odds with each other and their children. Both a rich and informative travelogue and a profoundly emotional memoir, Castles & Ruins celebrates the triumph of creative success while frankly appraising the often-terrible costs a family must pay for it.
