Eleven-year-old Fiona blames her older sister Arden for their family's move to the "quaint" (fictional) Massachusetts town of Lost Lake. Arden, thirteen, is a successful figure skater, and Fiona feels that her parents value her sister more than her. Finding solace in the town's library, Fiona discovers a mysterious book called The Lost One that tells the story of two sisters from that very town, one of whom disappeared a hundred years ago. The Lost One refuses to stay put, despite Fiona's best efforts, and it routinely disappears from her possession, only to show up at the library again. Together with a boy from Lost Lake, Fiona investigates the history of the two sisters and the legend of the fearsome Searcher that is said to snatch children from the town's woods. What starts as rather a cozy mystery -- small town, quirky librarian, strange book -- builds up to a spooky denouement with brief but very real peril the intrepid youngsters must face. While the shift in tone from the main text to passages of The Lost One feel jarring at first, the two stories blend together nicely by the end, and readers will be eager to learn the fates of both pairs of sisters. The realistic and picturesque details of Lost Lake capture small-town New England perfectly -- but with sinister history lurking behind every old landmark. (c) Copyright 2023.

A mysterious book leads a girl into a century-old supernatural mystery. When Fiona’s family moves across Massachusetts to Lost Lake, a small town that’s far closer to her older sister Arden’s figure skating club, Fiona resents both being uprooted and the constant focus on her accomplished sibling. To avoid spending hours sitting at one of Arden’s practices, knowledge-loving Fiona opts for a morning at the library, where she discovers a book called The Lost One that begins, “Once there were two sisters who did everything together. But only one of them disappeared.” Reading this book within a book, Fiona learns about characters Hazel and Pearl—relating heavily to younger Pearl, especially when she starts getting left behind, and knowing their story won’t have a happy ending. Fiona better endures slights from her family because she has the book to look forward to, but when she finally gets a library card, the book’s gone and isn’t even in the system. In response to a heartbreaking moment of being her family’s lowest priority, Fiona doubles down on solving the book’s mysteries—having determined its setting is Lost Lake—and finds increasingly spooky pieces of the puzzle. Although the two sets of sisters have different relationships and dynamics, the complexity of sisterhood links both storylines, resulting in nuanced relationships. The gore-free supernatural elements are more haunting than terrifying, foregrounding the characters’ journeys. Main characters default to White. Grab a flashlight and stay up late with this one.
