Kathy has answers for all of Sally's questions about life, about love, and about Billy Barnes, a local basketball star who runs the refreshment stand at the town pool. Billy's unfathomable, otherworldly cool puts him on a different planet - until a tragedy leaves Sally's life forever intertwined with his. Opening in the early nineties and charting almost two decades of shared history and missed connections, Notes on Your Sudden Disappearance is a dazzlingly unconventional love story that brims with unexpected moments of joy.
