A vividly felt love story from the bestselling author of The Wedding People.

“Heartbreaking and funny, often in the same sentence—a deeply felt, finely wrought, and highly satisfying novel. Alison Espach has created a family whose every sorrow, joy, and idiosyncrasy is utterly, vibrantly real.”—The New York Times bestselling author Claire Lombardo

For much of her life, Sally Holt has 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, a rising senior and local basketball star who mans the concession stand at the town pool. The girls have been fascinated by Billy ever since he jumped off the roof in elementary school, but Billy has never shown much interest in them until the summer before Sally begins eighth grade. By then, their mutual infatuation with Billy is one of the few things the increasingly different sisters have in common. Sally spends much of that summer at the pool, watching in confusion and excitement as her sister falls deeper in love with Billy—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 both a breathtaking love story about two broken people who are unexplainably, inconveniently drawn to each other and a wryly astute coming-of-age tale brimming with unexpected moments of joy.

This story perfectly captures the sibling dynamic of younger sister and older sister in a family, with older sister Kathy as teacher, and younger sister Sally as student, navigating being teen/pre-teen together. But what happens when one of them is ‘left-behind’ through a tragic turn of events? It is a story of guilt, great sadness in mourning, and redemption - told through the story device of the younger sister, Sally, talking to Kathy in sisterly confidence of ongoing happenings in their family and with friends, even after Kathy is gone. One of those friends is Billy, who had been Kathy’s crush since grammar school. Almost like a diary, Sally depicts how both girls focused their attention on him - observing him at school as a basketball jock, and being a summer pool concessions clerk, as he interacted with girls. By the time Kathy finally captured Billy’s attention herself, singing the national anthem at one of Billy’s games, they finally become official boyfriend and girlfriend. And both Kathy’s and Sally’s parents also like him, inviting him over for family meals. Sally even has a crush on him, a boy who has loomed large in both the girls’ imaginations. How the family, and Billy himself, navigate their relationships in the ‘sudden disappearance’ of Kathy, is a well-told, interior story over a twenty year timespan. It will stick with me long after the final page.

Notes on Your Sudden Disappearance is told in a unique, almost conversational style that instantly pulled me in. The way the story unfolds feels intimate and personal, making it easy to feel deeply connected to the main character. The writing captures the emotional weight of grief and change while still feeling authentic and human. It’s the kind of book that stays with you because of how close you feel to the voice telling it.

Really enjoyed. Brings out a lot of different emotions and perspectives. After reading so many pages of descriptive storyline matter, the way the book ended was disappointing. I would’ve definitely read a few more pages after everything that I had already read to have a better ending.
