Toward the middle, there are some explicit descriptions involving blood and gore and hacked up body parts, but in my jaded opinion, not very frightening.

Overall, the most frightening part of the book (for me) was the scene near the beginning when the protagonist’s little brother is being taken over by a Vour. Then the story sagged and suddenly picked up at the end (so much so that I want to read the second book just to see what’s up with a certain mysterious character).
