This wonderful challenge is being hosted in 2011 by Historical Tapestry. I finished the challenge this year by May I believe so I don't think I'll have too much trouble finishing it next year (though I will have a baby arriving in May!).
There are, as usual, different levels you can join at and I am, again, going for the biggest (I do love to read even though its been difficult lately!). I am going to join up at the Severe Bookaholism level which means I'll need to read 20 book from January to December. Easy. :)
Head on over to their blog to check it out and join up if interested!
