I've always been meaning to check him out - how technical are his books? Is it overdone with little characterisation or is it OK?
If you're a math geek,
Cryptonomicon is the book you've been waiting your whole life for. (Hmm, is that a wee bit excessive?) Not that there's a whole lot of math in it, but there's a whole lot of stuff that a typical math geek will really enjoy. This was the third Stephenson book I read, and the one that catapulted him from an author I really like to my
favorite author.
If you're not a math geek, well, I can't speak to that.
If you're worried about it being too technical, you should probably start with some different Stephenson, like
Snow Crash or
The Diamond Age. Pretty much all Stephenson is good, but good in different ways. It's also been said that the early Stephenson novels don't have very good endings. I won't argue with this, but I find the ride so interesting that I tend not to care so much about the ending.
As far as character development goes, I think he's typical of scifi authors, who often have different fish to fry. Stephenson's most well developed characters are probably in
Anathem, which is a very thinky doorstop of a book.
