Ask HN: Technical books for the BART

I am on the hunt for a good CS related book I can read on the BART without needing to crack open a computer to do the exercises. I have read quite a few non fiction and fiction books but miss books that are in my field. I tried the SICP but it was hard to get a lot out of it without writing the code itself. Last time I enjoyed a book in this domain on the BART was the Heads First Design Patterns where the code was simple enough to focus on the prose instead.
