Gibson is the first thing that springs to mind. The first part of the book is breathtaking - loads of things to take in as the new world unfolds around you. After it slows down, and winds up to a logical conclusion. Very nice - a bit heavy at times. The book has received many sci-fi awards and is available for free amongst other places here www.antipope.org/charlie/blog-static/fiction/accelerando/accelerando-intro.html . Definitely a good read, even if I didn't enjoy the third part as much as the first 2.
