Escape from Mr Lemoncello's Library
This book was a lot of fun, with conscious echoes of Charlie and the Chocolate Factory, but with books instead of sweets. A team of lucky kids win an overnight stay in a brand-new, whiz-bang library built by a famous inventor; but there's a catch. They have to solve the clues Mr Lemoncello has planted in order to get out! Naturally, the clues are literary ones, but even our hero Kyle, who doesn't enjoy reading, can use his wits to piece together the solution.
If Grabenstein succeeds in pointing any readers to the many books he references in this enjoyable romp, then he has truly performed a service. Mr Lemoncello also speaks in dialogue lifted from famous children's books, which adds a layer of fun for the adult (or widely-read) reader. Apparently this book has also been made into a movie, though I haven't watched it -- no doubt someone in my very conscientious book group will have done so. I'll wait for their verdict before I give it a go.
