Unfortunately, it's not a good book for someone who never program before. It more structure for adept programmers who want to learn an other language. I wouldn't say that you will master the common lisp after you read the book but you will have understand a lot of things.
The chapters are progressive and you use concept that you learned in the previous chapters. The only thing that I don't like is that the examples are not easy for people who never programed in Lisp (or common lisp) for the reason that doing a specific way is not well explain.
