Wow. My students loved this book.
The plot is simple, easy to follow, and linear. There is a big chunk of the book that is told via a narrated story (flashback), but other than that it unfolds sequentially. Instead, of plotting the book, we decided that we would visualize the characters and their connections to each other. The author went to great care to explain how everybody knew everybody else.
It was also great for making inferences. There was a lot of intrigue in this book, and things left unsaid. What is the Plan? What does NIMH stand for? What will happen to Mrs Frisby's house? Who was Jonathan, and how did he die? Who are these rats? Where did they come from? The author does a wonderful job of teasing you with pieces of the puzzle, one little piece at a time. You may or may not find the answers to all of your questions.
I love reading a class a book that I have never read before, but I recognize that it can sometimes NOT work. I have started books that I had not read before only to find they were boring, and the class was not into. When I chose a book I have read, I usually know they will like it.
This was fun though. Being on the edge with them, making inferences and charts, trying to guess what would happen next.
Resisting temptation to sneak a peak ahead....
