The characters are well worked out and distinguishable. Some characters transformed from 'bad' to 'good' as they experience the shocking reality in area 187. People that hate each other in the beginning grow together. I liked some characters very much. What bothered me a little was the super-hero who was the 'uber-guy' all the time, like Rambo or so.
The fact that the heros go into the area from save outside took a little bit of thrill. While reading I was almost always sure they would make it.
