In the misty highlands of post-war Scotland, Elspeth McDonald—known to all as "Miss McDonald"—has spent thirty years tending the village library of Glen Argyll. When a mysterious letter arrives claiming inheritance of a farm in County Cork, Ireland, her carefully ordered life unravels. Armed with little but a satchel of borrowed books and her grandmother's unanswered questions, Elspeth journeys across the sea, uncovering family secrets, a wartime betrayal, and an unexpected romance. "Miss McDonald" is a tender tale of belonging, reminding us that home is not where we are born, but where we finally choose to stay.
