Escape from Mr. Lemoncello"s Library

The 12-year-old Kyle and his classmates could not even think about what the holiday would turn out to open the new library, which was built by the great Luigi Limonchello, an unsurpassed inventor of computer and desktop games. In honor of his birthday, the chief librarian came up with a real quest - the guys were locked for 24 hours in the building, inviting them to find a secret exit from the library. Kyle and his friends have exactly 24 hours and encrypted tips - they are deftly hidden literally everywhere: in books, in archival boxes, on the ceiling and even on reader tickets. How will the night end in the library?
The book is the bestseller New York Times.
