This is Book Riot's Read Harder 2025 challenge! I did not create it, I just thought it would be fun to track on Storygraph. I do not have a paid subscription to Book Riot, so I don't have access to the bonus challenge, sorry! You can look through their website and sign up for their newsletter, which has more info. There is another user on Storygraph who has put up previous years, but I didn't see them upload 2024 or 2025.
