Fantastic story - I thought both books were equally brilliant. Took me a while to get into the second with the timeline shift, but absolutely brilliant overall.
I tweeted Justin Cronin t'other day regarding the release date on Amazon for City of Mirrors (they have it as October this year) and he replied! Sadly it is not coming out in October, but if it's half as good as the first two, it will be more than worth the wait.
I believe Ridley Scott purchased the film rights, before the first book even came out. It's gone a bit quiet on the film, last I heard Matt Reeves was directing it.
