This year, I’m not planning on participating in as many reading challenges due to lack of time.
The two challenges I am doing are my 100-books Goodreads challenge and the /r/Fantasy 2018 Bingo. I still have my long-term “Read Around the World” challenge but I’m not focusing strongly on that at the moment.
I may do occasional mini-challenges later, but for now I’m busy focusing on reading the review copies that I have and just working through a huge backlog of books that I want to read. Once I’ve got through all those, I may add more challenges but for now I definitely don’t need more books for my TBR pile!
