It's more puzzle-hunt young adult fiction by Jody Feldman. You remember how I liked her Gollywhopper Games book, aside from the magical realism parts? This book has a school that's also somehow the headquarters of a secret society of everyone from St Louis who's ever done anything cool and they arrange fundraisers for the school that the kids all love and... And there were some puzzly bits, but man I had a really hard time getting past the unbelievable-premise bits. It might have helped if this book's game was team-oriented; Feldman's shown she can write about that pretty well. As it is, our protagonist has friends, but he must ditch them for the most part when he's puzzle-hunting.
