“Grab a flashlight and stay up late with this one.”—Kirkus Reviews

Once there were two sisters who did everything together. But only one of them disappeared.

New York Times–bestselling author Jacqueline West’s Long Lost is an atmospheric, eerie mystery brimming with suspense. Fans of Katherine Arden’s Small Spaces and Victoria Schwab’s City of Ghosts series will lose themselves in this mesmerizing and century-spanning tale.

Eleven-year-old Fiona has just read a book that doesn’t exist.

When Fiona’s family moves to a new town to be closer to her older sister’s figure skating club—and far from Fiona’s close-knit group of friends—nobody seems to notice Fiona’s unhappiness. Alone and out of place, Fiona ventures to the town’s library, a rambling mansion donated by a long-dead heiress. And there she finds a gripping mystery novel about a small town, family secrets, and a tragic disappearance.

Soon Fiona begins to notice strange similarities that blur the lines between the novel and her new town. With a little help from a few odd Lost Lake locals, Fiona uncovers the book’s strange history. Lost Lake is a town of restless spirits, and Fiona will learn that both help and danger come from unexpected places—maybe even from the sister she thinks doesn’t care about her anymore.

New York Times–bestselling and acclaimed author Jacqueline West weaves a heart-pounding, intense, and imaginative mystery that builds anticipation on every page, while centering on the strong and often tumultuous bond between sisters. Laced with suspense, Long Lost will fascinate readers of Trenton Lee Stewart’s The Secret Keepers and fans of ghost stories.
