The Key That Opened Yesterday

Maya Reyes trusts maps because maps do not lie. Then she finds a hallway that should not fit inside Briar Glen Public Library - and a hidden Lost & Found room filled with impossible objects. A brass key appears with one address: 17 Alder Street. The problem? No such house exists. At 4:17, the key opens a door into Yesterday, where twelve-year-old Elena Vale is trapped inside a frozen version of her family's home. Everyone in town has forgotten Elena, her family, and the house itself. With the help of rule-loving Priya, joke-cracking Theo, and sharp-eyed Eli, Maya follows a trail of vanished records, strange paper tags, and a man in gray gloves who believes some truths are better forgotten. If the Lost & Found Club cannot return what was lost before the last bell, the Vales may disappear for good. The Key That Opened Yesterday is a fast, eerie, funny middle-grade mystery about friendship, memory, belonging, and the truths worth bringing home. Perfect for readers who enjoy magical libraries, secret rooms, supernatural mysteries, and adventurous friendship stories.
