Some parts of the book are slow because of the academic nature, and because Johnny can talk for quite a bit. Still, I found the writing to be high-quality, and overall enjoyed spending time in Johnny's head—he may not be lovable, exactly, but his character development is fascinating and his voice is interesting. And the slow moments pay off in all the scenes overflowing with intrigue, emotion, horror, and suspense. The book's depth seems to be as deep as the labyrinth itself.
