I just finished this book like 3 hours ago, and I've already forgotten pretty much everything that happened. I think I remember thinking that Arthur was finally doing something rather than just sitting there while things happen to him and for him, buuuut I don't remember.
I'm pretty sure I would like this better if I were a 10-year-old boy. It's entertaining and exciting enough to capture the attention of people that age, which is what it is meant for really—not 23-year-old girls—so I guess it achieves its purpose.
