Ask HN: Update for You Can Be a Stock Market Genius by Joel Greenblatt?

I recently read You Can Be a Stock Market Genius by Joel Greenblatt and really like the style of the book and the ideas presented in it. I am learning about event driven investment, and want to read more about it. Greenblatt's book is almost 20 years old at this point. The basics are still the same, but some things have also changed in the last 20 years. What other books on the subject would you recommend. Thank you for the help!
