Okay! Well, it's time to move away from books you encountered in school or childhood, and pick up a book that has been around for a while.
This week's challenge is:
3. A Book Published Over 100 Years Ago
Now, that includes everything written before 1918, so you've got a few to choose from.
By the way, you'll notice that most of these challenges don't specify "fiction book" or "novel" - so you can choose any kind of book you like, so long as it's a little long in the tooth.
And we've had a few people say the idea of all 52 books is a bit daunting - but never fear! We don't mind how many books you read this year. The challenge is just designed to encourage you to think about reading a book you might not have read without the prompt.
Feel free to jump in and out of the challenge as you go along, and see how many books you can fit in.
