Simon Winchester - The Professor and the Madman: A Tale of Murder, Insanity, and the Making of the Oxford English Dictionary
If you know me personally or almost personally, then you should be aware that I am quite mad. I have a heavy obsession with the alphabet, inventing bizarre systems that rule just about anything in my life and catalouging things. It is quite obvious that a book about a lunatic and creating Oxford English Dictionary would be a winner with me. And it was.
However, it wasn't perfect. Winchester performed some weird narrative experiments. For example, he started off with a really exciting scene, then er... repeated that scene word by word in the middle of the book. And then... a chapter or so later, he said it actually never happened. This is a non fiction book!!
Also, Simon Winchester is obviously psychic because he can tell exactly what everyone was thinking and feeling ages ago. The conviction which he states it all with is imperturbable.
It's all forgiven, though, because any book that involves someone cutting their penis off (ESPECIALLY non fiction) can't get anything less than four stars.
