What fiction should I read first?

I have read pretty much nothing but MoR and books I didn't like for school, so I don't really know what my preferences are. I am a mathematician and a Bayesianist with an emphasis on the more theoretical side of rationality. I like smart characters that win. I looked at some recommendations on other topics, but there are too many options. If you suggest more than one, please describe a decision procedure that uses information that I have and you don't to narrow it down.
