Escape from the library of Mr. Limonchello. Grabensstein K.

12-year-old Kyle and his classmates could not even think about what the holiday would turn out to open the new library. The great Luigi Limonchello, an unsurpassed inventor of computer and board games, made that, being in the library, the guys were in the real game: the one who will be the first to get through a secret exit from the library. But where is he, this way out? 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?
