After reading this book I honestly believe it should have already received a film adaptation and I'm shocked that more people haven't discovered it. The book itself is like a good mixture of the themes and atmosphere of things like Harry Potter, Hotel Transylvania, Halloweentown, even a Monsters University etc. (I'd assume the sequels as well but I haven't read them just yet). I won't go into too many details because I don't want to ruin the story with spoilers, but I will mention a few things. One of my favorite things in the book is the concept of Automatic Writing, which of course in modern pop culture is simply when someone channels a spirit who uses that person's hand to write something, but Paolucci's idea of one person (or monster) channeling a spirit to deliver a message to another person. I love that. The characters are written very well where you can pretty much identify with each of them. Surprisingly, I found myself identifying with Logan more than Sally. Which is admittedly very different from what I would assume most people would identify with. Although it was a bit long, the intro to the novel was insightful and helped paint the imagery and tone of the rest of the novel. In that aspect, the choice to tell the story in the first person worked perfectly because otherwise it may feel as dry as the exposition in The Silmarillion could be. On the flip side, at times I had a hard time believing I was reading something told from the point-of-view of a thirteen year old girl-- monster or not. However, I believe this is more because I know the author personally so at first I kept imagining him instead of Sally. But I will say, that feeling did go away for me towards the middle of the novel. Holistically the structure was very interesting. We start with what is essentially a prologue, to a long first and second act, but once we get into the third act, the book is nearly over. Personally for me the end battle was something that I wanted to read more of. I hear that the tone shifts to being a bit darker in the next two, so maybe my thirst for more of that story-line will be quenched. Overall this is a great book and I highly recommend it to anyone who enjoys young adult fiction. And I'm not just saying that. Read it for yourself!
