Worst part--it doesn't end! I know it's a part of a series but it's really more of a chapter. Most series books have their own beginnings and endings with the main characters and certain themes linking the books, a la Magic Treehouse.
It was funny, though, and the kids were definitely more interesting than those Magic Schoolbus or Magic Treehouse goody-goodies, so it's got that going for it. I'll have to see if my student's dig them.
