If you're a fan of the Tao Te Ching, you might want to stay away from the Left Behind series of Christian post-apocalyptic fiction. Hated Dream of the Red Chamber? You might love Bridget Jones: The Edge of Reason, The Divine Secrets of the Ya-Ya Sisterhood, or A Million Little Pieces. Genji fans apparently steer clear of books about shopping and Christianity, and it looks like Confucius will not be among the Five People You Meet in Heaven.
