When I was a kid, I really loved it when the English teacher would give us a list of 100 or so books to read. It was nerdy and challenging.
So if you need a challenging book challenge, let me suggest the Book Riot Book Challenge. Plus, there’s a PDF that you can print out and check books off. You can also use the same books for your Goodreads challenge if you want.
At the moment, I’m reading “Hood Feminism” by Mikki Kendall. It has definitely been an eye opener for me. No regrets.
The point of the challenge is to read outside of the box. Read books that you wouldn’t normally read. Read books by authors that you have never heard of before. Expand your reading horizons.
