I really enjoyed this book. I thought it was an interesting examination of Cormier's work. I love getting insights. It reads almost like someone's dissertation, but is a lot more interesting and engaging. The notes at the end of chapters will aid readers looking for additional information. I also liked the book's design.
Having said that, I don't know if teens will be inclined to read this type of book unless it is assigned. Actually, I don't think assigning it as a supplemental reading for an English lit or even a writing class is a bad idea.
