I've always liked this author and Flashforward was the first of his novels I ever read, in an afternoon with Ken Grimwood's Replay, of all things. I enjoyed the first 90% of the title and the mystery of the killer was an intrigue. the technology was also fascinating, of course; this was written before Cern's LHC ever did anything, as far as I am aware. I could never really get on with the whole transcendence idea, though, so found the ending a little lacking for my personal taste.

Blackstone Audiobooks have a good version of this, I read it as an OCR at the time and have only heard narrated portions.
