I must be lucky with my book series these days: they've all ended quite satisfyingly. 
 Demon Road is no exception to the rule: American Monsters delivers both plot-wise and emotionally, while giving us plenty of scary creatures around the way. 
 We're back on the road and with Amber's point of view. Even though I must say that I didn't enjoy this as much as Demon Road, it was still really cool. I liked the monsters (mostly), and I liked Amber's development. A few scenes seemed a bit pointless and/or over-the-top, but overall it didn't bother me too much. 
 As I said earlier, I'm quite happy with the ending. It wraps things up pretty well, while being quite action-packed. Maybe not as punchy as I would have thought, but still. 
 This might not be the best book in the trilogy, but it's still a very good one, and I'd recommend you check the whole thing!
