Two Can Keep A Secret by Karen M. McManus

After twins Ellery and Ezra move to the eerie town of Echo Ridge to live with their grandmother, they find a community haunted by their aunt’s long-ago disappearance and a homecoming queen’s unsolved murder. When ominous threats target the new homecoming court and another girl vanishes, Ellery—an avid true-crime fan—teams up with Malcolm, the brother of a former suspect, to dig into the town’s buried secrets, navigating tangled loyalties, small-town gossip, and escalating danger as they race to uncover the truth.
