Ask HN: Business analyst, to BI analyst, books

Hi HN, I'm a BA, working as a consultant, after a failed startup, self learned python, sql, a bit of html, and I want to pivot to business intelligence, and continue working as a freelance consultant in corps and gov agencies. What do you recomend I should read ? I can learn on my own very fast and effientlty. And if you can suggest me some books to become a better BA, that would be great too! I'm based in Québec city.

thanks!
