Any recs for books that focus on core skills?

I’ve hit a point in my studies where I’m being told that I need to go back to the basics. Having read a few 101 Wiccan and non-Wiccan books, I feel they didn’t quite cut it for me since they were more of a sampler platter of magical miscellany. I would greatly appreciate any recs, no matter the medium!

On a side note: I’ve read about Jason Miller here on the forums and would like to know your thoughts on his works. Was curious if they had the same tone as the blog he maintains? I’m interested in all his books, but I’m wondering which one to start with.
