Looking for a book on c++ isometric game programming

The title says it. I am going on a holiday but want to learn more about programming, hopefully on the beach.. I am familar with pytyon, not so much with c++, kinda beginner level looking to learn advanced level.

Anyhow. I am planning on a creating a c++ based project zomboid like game. Fully isometric, opengl library, 3D character rotation. That kind deal.

Algorithms, general language, methodical implementations, all of it that is necessary, I am a solo now and am in it for the long run. This isn't my first large project.

I want to know some things about graphics, mainly how to implement them but not about actually making art. I will outsource all of the graphic design and also audio.

Any suggestions for books? Multiple suggestions? Also if you know a subreddit better suited for this question, do please let me know, this is just a quick grasp in the dark while I pack my suitcase and get on a airplane.
