Lisp from Nothing, Second Edition

Under “The Intended Audience” (page 10 of the PDF sample on the site), it says that this is not an introduction to LISP and that it would be more enjoyable with some prerequisites.

Where does one — who has no knowledge of these prerequisites or about LISP (except that the latter has been heard in programming circles as something esoteric, extremely powerful, etc.) — start, before reading this book?

If you prefer hands-on learning, How to Design Programs is pretty good resource for the foundations, with lots of examples and exercises: https://htdp.org

But learning the basics of lisp is more like a side effect, the focus is on program design.
