I can't be too harsh. It is a children's book and not the type of children's book that can entertain adult readers as well. I'm thinking of the Harry Potter series and Charlie and the Chocolate Factory. It was an easy listen, interesting enough to keep my brain mostly engaged while doing chores around the house. But the characters seemed flat and mostly unsympathetic. Most of them seemed frustratingly passive and/or stupid as well. Still, it was a fairly clever and complete alternate world, and kept me just interested enough to want to find out what happened next. I won't be reading the rest of the series.
