I had posted this earlier this month about something called The Book 100. Basically, it's a list of 100 books that are within a genre in which you are personally interested in writing. I cheated a little a chose sci-fiction/fantasy and will be reading fifty books from each genre. Rather than a challenge, I'm considering this to be a goal, instead, which will be kept track of in the "Extras" section of my blog. There's no time limit or time frame, just an eventual goal of 100 books.
I've also decided that, rather than compile a list ahead of time, I'm just going to add books to my list as I read them until I have fifty of each. It saves me time and makes this a lot more fun and spontaneous. Keep checking back to see my reviews of these books.
