As much as I did not love this book, I can certainly imagine a handful of students who'd enjoy it quite a bit. Students for whom reading is usually a boring chore.
Think: a cartoon for middle-schoolers with paper thin characters, an unbelievable save-the-world plot, and sarcastic, self-deprecating first-person storytelling by a kid who's quite self-absorbed.
Think: yeah, I know a few kids who will LOVE this.
And the reading level?? EASY. Fourth-grade.
