The first challenge I ever participated in and the first one I joined this year was the 2012 Mount TBR Reading Challenge. I had already planned to read a lot of books that I already owned in 2012, but this challenge was a great motivator. I signed up at the Mt. Vancouver level: Read 25 books from your TBR pile/s.
I completed this challenge on July 4, 2012, when I finished reading The Sleeping-Car Murders
by Sebastien Japrisot. However, I continued tracking novels I read this
year from my To Be Read stacks.
At the end of last quarter I had completed 39 books for the challenge, and this quarter I read 12 more books that count toward the challenge, for a total of 51 books (out of 80 books read this year). I finished The Vault by Ruth Rendell a couple of days ago, and have not reviewed it yet. I am currently reading a book from my TBR stacks, so I should reach 52 books before the end of the year. My complete list is at this post.
I wish I could say that reading all those books made a big dent in my TBR stacks, but I bought many more than 52 books in 2012. On the other hand, if I had not read those books, the situation would be worse.
I have already joined the Mount TBR Reading Challenge for 2013, and hope that I do as well.
