"Breaking the Social Media Prism: How to Make Our Platforms Less Polarizing" by Chris Bail. I have always had a difficult relation with social media. I hated them from the beginning and my discomfort has only grown over the years. This book was an eye opener to me and clearly explains why social media leads to polarizing and it's not what you expect. To me this was one of the most thought provoking books I read this year.
