Washington, DC, 1950. Everyone keeps to themselves at Briarwood House, a down-at-the-heels all-female boardinghouse in the heart of the nation’s capital, where secrets hide behind white picket fences. But when the lovely, mysterious widow Grace March moves into the attic room, she draws her oddball collection of neighbors into unlikely friendships. Grace’s weekly attic-room dinner parties and window-brewed sun tea become a healing balm on all their lives, but she hides a terrible secret of her own. When a shocking act of violence tears the house apart, the Briar Club women must decide once and for all: Who is the true enemy in their midst?
