“To celebrate the grand-opening of Alexandriaville’s state-of-the-art new public library, eccentric billionaire game-maker Luigi Lemoncello invites twelve 12-year-old contest winners to a slumber party. The lock-in becomes a reality game to escape the library by using its resources, finding clues, and solving puzzles, with the winner becoming the spokesperson for Mr. Lemoncello’s game company. Young readers can solve the puzzles, too, while enjoying a fun-filled mystery that celebrates teamwork, perseverance, and the love of books.”
