Sally Holt has always been mystified by the things her older sister, Kathy, seems to have been born knowing. Kathy has answers for all of Sally's questions about life, about love and about Billy Barnes, the high school basketball star who runs the refreshment stand at the local pool.

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.
