I’m sure a lot of people have their opinions about what the best introductory lisp text is. I won’t add to that list since a google search will give results from reviewers far more eloquent than I am.

What I would like to suggest is that once you basically “get” how the prefix syntax works, and how to process lists, Doug Hoyte’s Let Over Lambda (https://letoverlambda.com/textmode.cl/guest/toc) is a book that can really help you -learn- lisp, to fundamentally understand what makes lisp so powerful compared to other languages. Incredibly perspective-expanding content when I first read it, and largely references many of the “great” lisp texts that helped build the language and its community into what they are today.
