SICP is a fantastic and difficult book. I got through about 50% and have a much bigger appreciation for programming now. FYI - The original was written in Scheme. There is a newer version based in python which I haven't tried. Edit: The python version is highly contested. Scheme is the more difficult and therefore the best way to understand these principles.
