I’ve written a few books over the years:

LazyVim for Ambitious Developers My current work in progress, a book introducing the excellent LazyVim distribution to developers new to modal editing. I am publishing this online free, and hope for support on Patreon. Physical and Ebook editions are planned.
Python Object Oriented-Oriented Programming launched my career, both as a programmer and as a writer. I wasn't able to do the revisions for the fourth edition, and passed the torch for this latest version.
Creating Apps in Kivy covers the exceptional Kivy framework for developing efficient mobile and desktop apps in Python. Note: The book is still relevant, but decidedly outdated.
Hacking Happy Hacking Happy was about applying programming and IT concepts to mental health. I've taken it off the market for reasons discussed in this post.
