“A worthy successor to . . . Willy Wonka.” —Booklist, starred review
When Kyle learns that the world's most famous game maker, Luigi Lemoncello, has designed the town's new library and is having an invitation-only lock-in on opening night, he's determined to be there! But the tricky part isn't getting into the library—it's getting out. Because when morning comes, the doors stay locked. Kyle and the other kids must solve every clue and figure out every secret puzzle to find the hidden escape route!
