This book is set up for teachers. Not common teachers, but teachers who are wanting to help their students reading. The book discusses how reading classic literature can be very difficult because language use is different, terms are different, and some things that would have been back knowledge of the time is no longer known. Lemov points out that giving prep text, such as a short story or article that bridges the gap of information. Building back knowledge really helps most literature because understanding more about a story really does make the story more enjoyable.
Not being a teacher some of the terms used I was not familiar with. This book for me though was highly interesting to think about how teachers really teach literacy.
