Book related questions

If you have a book related question, check out the blog. There are over 230 posts (as of Feb 2020), and one of them will very likely expand on your question. If you can’t find there what you are looking for, however, feel free to get in touch via the blog comments. I do read them.

Other questions

The best way to ask me a question, or get in touch, is through the blog. I would love to give out my personal email, if not for the fact that I’d like to avoid spam emails. You get it.
