The Passage by Justin Cronin

6 year old Amy is abandoned by her desperate mother with a group of nuns after killing a trick who was taking her to a fraternity house.  Deep in the mountains of Colorado army scientists are trialling use of a virus found in the jungles of Columbia to create supersoldiers of immense strength, bloodthirstiness and longevity, vampires in all but name.  After 12 subjects the scientists want a new subject, they want Amy, and after treatment she becomes something new.  Inevitably the worst happens, the 12 get loose and turn everyone they bite into one of them, 'smokes', 'virals' or 'dracs'.  The United States turns apocalyptic.

Move forward a century, Peter lives in a fortified community, he has never seen the stars because at night floodlights are switched on all round the perimiter to keep the smokes at bay.  He is one of the Watch and is waiting for the return of his brother, taken up by the smokes on a visit to the generators.  For some reason, the smokes always come home.

This could have been a brilliant dystopia, it has elements of Shymalan's 'The Village' and good post apocalyptic novels but the characters aren't well deliniated, apart from Amy and ex-nun Lacey they all blended together for me.  There are too many cliches, vampires rule the world and humans become just meat, mad scientists ruin the world, etc etc.  Disappointing ultimately
