I am overall glad that I picked up The Fireman, however I enjoyed NOS4A2 much more. Which sucks because I hate to compare books- but it was a tad inescapable for me at the moment.
I would put this one among the post-apocalyptic, science-fiction books with a tinge of horror. The kind of horror that just sizzles and pops throughout that makes you jump away from the burner- but only for a second. Joe Hill inserted a lot of social commentary on contemporary issues- refugees, for one. What stood out for me was the inevitable result that comes from naive, scared, and powerless people in large groups with one over-ruling leader.
Would I recommend this to my sci-fi and apocalyptic readers? Yes. Horror fans? Maybe.
