I too recommend SICP. It is great, especially if you haven't been exposed to much CS stuff already. I have found newLisp : http://www.newlisp.org/ http://www.newlisp.org/ very good. It runs on all common platforms and the net-eval mechanism is excellent for distributed computing.

Read some of Paul Graham's essays to get a feel for the power of macros.
