Haunted by his youthful romance with Dara, gifted and sensitive violinist Adam must confront his past to find a way forward. At the Philadelphia graveside of his mother, Adele Pearl, wife and partner in a celebrated two-piano team, his father, Victor, mourns the loss of both his wife and musical career. As Adam reflects on their relationship, he realizes his mother was absent in ways that truly mattered. Struggling with the emptiness left by a series of failed relationships with talented women, Adam grapples with his connection to Dara, an English professor burdened by her own divorce and blind to what she lost in him. Martha Anne Toll's Duet for One weaves a poignant narrative of loss, connection, and the enduring hope that love can be found where life resides, following her acclaimed debut, Three Muses.
