Gr 4–7—Bibliophiles unite! Melvil Dewey is alive and well and residing within Mr. Lemoncello's new library. Billionaire game-maker Luigi Lemoncello wants to pay homage to his childhood library by constructing a technological marvel in his hometown that went without a library for 12 years. He invites a dozen 12-year-olds to a lock-in at the new building, and when they arrive they find the eccentric game-maker has offered them a further challenge-if they can find their way out using only what's in the library-they will become the new spokesperson for Mr. Lemoncello's company. Kyle Keeley teams up with other students as unlikely alliances form, some children's true (not so nice) personalities emerge, and suspense builds while the kids enlist the aid of Mr. Lemoncello's childhood librarian, an Electronic Learning center, and book clues and references galore. The story feels like a cross between a reality show, an online game, and a tightly woven mystery. Dewey Decimal clues will hook librarians and teachers, while book lovers will delight at myriad references from Mr. Lemoncello, such as, "And now, I must return to my side of the mountain… I have great expectations for you all!" Book and game lovers alike will delve into this delicious tale and put on their thinking caps.—Michele Shaw, Quail Run Elementary School, San Ramon, CA
