There are two big sci-fi book releases I've been hanging out for this year. The first is Gibson's Pattern Recognition and later this year will be Neal Stephenson's Quicksilver.
So this one was pretty damn good! Nothing to blow you away but I quite enjoyed it. I don't think it grabbed me as much as Idoru, but it was definitely an interesting story and explored some good ideas. It's also a very timely book, exploring themes around September 11 and ideas stemming from new online movements.
All in all, an interesting read and worth the wait. My copy will be going to the library shortly unless I hear from someone who wants to borrow it directly from me.
