What are some fiction books about mathematicians/ other scientists ?

It seems to me rather difficult for writers to create good book books on this subject, I know quite little, some . Some years ago I thought there are were no such books at all. There are many reasons: it is difficult to describe the process of discovery and describe it in the exciting way. The subject has narrow audience and not the way to make best-seller...

The comments

Comments on how do authors try to avoid these problems are also welcome, e.g. The movie "A Beautiful mindMind" is a (beautiful for me) example, where the story of mathematician was mixed with love and spy stories to make it interesting for general audience, well not so much preserved from mathematician's story, but nevertheless I am quite positive about it.
