Lush Library discussion

If you see any interesting reading challenges (or think of any new ones) share them in this thread please.

I'm going to look around tonight and list some challenges here.
This year I'm concentrating on reading books I've been meaning to read for a while but I really like the sound of the travel challenges (around the world in books and around the U.K. in books). I might start them without a completion date and see what countries my current 2 lists tick. I've also seen a 10 genres challenge that I'm interested in taking part in. I think I'm quite a varied reader and it'd be interesting to pay attention and then broach the areas I don't read. I know that I don't really read biographies as much as I'd like.
