Two weeks from tonight, on October 21, 2017, folks will be in the thick of Dewey's 24-Hour Readathon. This is the 10th fall readathon (though I've only been participating since 2015). I am very much looking forward to having Halloween Bingo help build my readathon stack.
Don't be dissuaded if you can't clear your schedule. Many folks (myself included) do NOT even attempt to get to 24 hours of reading/blogging/book-related social media.
In the early days, Readathon was blog-based. These days much of the action is on Twitter, but regardless of where you participate, it's still a great book party. The feeling of being part of a WORLD-WIDE community that is all reading together at the same time is like nothing else*
Signups are found HERE
*There's a shadow of the same feeling here on Booklikes, but I find it's even more intense during Readathon.
