I'm going for level 4 - Wonder Woman, which is at least 20 books by women writers in 2014. Frankly if I can't read at least that many books written by women then I need to hand in my girl-card.
I'm also going to go for diversity, and read as widely around the world as I can because, well, diversity is good.
First up, optimistically, is The Luminaries by Eleanor Catton, which is the biggest book in the world.*
*The Luminaries is not actually the biggest book in the world.
