I really like Woodrow's work, especially Pet Wars, and there are not enough books about field trips. Not that my students ever take them, thanks to budget cuts, but they are always fun both to go on and to read about. This is a bit different from Woodrow's other school stories in that it has a Charlie and the Chocolate Factory or Mr. Lemoncello's Library vibe to it, with funny inventions, odd occurrences, and a mystery to be solved. The relationships between students evolve in realistic ways. The cover is fantastic. More books should have Slinkies on the cover!
Readers who enjoy lightly humorous, realistic fiction should definitely add this author to their list of books to explore.
