I just finished reading Surely you're joking Mr. Feynman. I first read it when it came out in the '80s and had been meaning to read it again for quite some time. Feynman's second auto-biography is even better, IMO, What do you care what other people think? Of course, both miss the mark of the OP, who is looking for fiction. However, they do live up to the oft-stated comment about fiction being stranger than truth.
