Two Can Keep a Secret by Karen M. McManus
The Setup: Ellery and her twin brother, Ezra, have never wanted to live in Echo Ridge, Vermont. But when their mother enters rehab yet again, they have no choice but to move in with the grandmother they barely know. Echo Ridge is a small town with a dark history: twenty-five years ago, Homecoming Queen Lacey Kilduff vanished and was later found murdered. Five years ago, another Homecoming Queen, Declyn's sister Sarah, disappeared and was never seen again. Now, as the town prepares for another Homecoming season, the threats are starting again.
The Complication: The day after Ellery and Ezra arrive, a mysterious message appears: "Your girlfriend hasn't turned up yet. Too bad for her. She had so much to live for." Then another girl goes missing. Ellery, who has always been obsessed with true crime stories, can't help but investigate. But Echo Ridge doesn't welcome outsiders poking into its secrets—especially not the niece of Lacey Kilduff's prime suspect, who still lives in town.
The Conflict: As Ellery digs deeper, she discovers that everyone in Echo Ridge has something to hide: her grandmother, the town golden boy, the quiet girl next door, and especially Malcolm, the brother of the missing Sarah, who is both her ally and a suspect. The closer she gets to the truth, the clearer it becomes that the killer has been watching all along—and they're not done yet.
Key Themes: A gripping YA thriller about small-town secrets, twin siblings, and the terrifying question of whether history is doomed to repeat itself.
