Okay, so I dropped everything else to read this book for the book prize I'm helping to judge. But I LOVE Calvin and Hobbes, and for there to be a young adult (technically middle grade, I guess?) novel about Calvin and Hobbes made me geek out a little bit.
Calvin deals with heavy themes and a pretty lighthearted manner. Of course, I appreciated the humor from the comics, and when Calvin begins to question everything he sees provides a legitimate insight to how his disorder affects him. It was well-written, although I wish it was longer and went more intimately into the characters and their stories, because right now, we're barely scartching the surface. The love story between Calvin and Susie felt forced because I didn't know either one of them well enough to believe in it, and it felt a little more like insta-love than true love, you know?
Also, I can't say how well the schizophrenia was handled, because I don't know anyone personally who has been disagnosed with it. I wonder if it's significant that the doctors say Calvin has auditory hallucinations, but he actually does see Hobbes on a number of occasions--all occasions, actually, even when it's just a flicker out of the corner of his eye. And the idea that you can take a trip across a frozen lake and that will *mostly* cure your mental disorder was probably not intended by the author, but that's the way it kind of came across.
Anyway, all in all, it wasn't long enough for me to develop a significant attachment to anything, although I did enjoy it while I was reading (one sitting in an airport).
