I just got myself Writing Interpreters and Compilers for the Raspberry Pi Using Python for Christmas (mainly to learn more about Raspberry Pi assembly). It's very accessible. First half of the book is a breeze, then the difficulty goes up a bit.
Relatively light on theory, which is a conscious choice by the author. The whole approach starts more from the applied angle than the theoretical, with the latter serving the former. It does discuss CFGs, for example.
Welcome! Stumbled across it when someone else here (or perhaps on a programming subreddit) referred to this professor as writing really accessible books.
(BTW, based on other comments I've seen by you before I doubt it will contain a lot of challenging content for you. But perhaps the writing style itself is interesting)
