I picked it up and it was very good read. I had to abandon it less than halfway because of other responsibilities that I have. I very much plan to go back it. This book is very good, and I recommend it.
SICP is always a classic and worth going through in any stage of your life.
There are also suggestions in Common Lisp website for books [1].
For Common Lisp I like Norvig's Paradigms of Artificial Intelligence: case studies in Common Lisp because it has short examples of how Common Lisp programs can be put together in practice.
And I think Common Lisp is worth learning because it is an underlying element when it comes to other Lisps like Racket and Clojure and eLisp...they either adopt what Common Lisp does or reject it, but they don't ignore it.
