The only thing that wasn’t really clear was when people could see the Shadowhunters or not (they are demon hunters and people are not supposed to see them), I didn’t understand this very well. The story is well constructed and you never get bored. I had a problem at the beginning because there was too much action and not enough thoughts. It felt like a succession of actions where you didn’t get the feelings of the characters enough. I felt a change around page 300 or a little before, after they went to the vampires’ lair. Much more feelings, still a lot of action but it was better written since that part of the book. Maybe it’s just my imagination but I really felt a change.
Anyway, a really great book if you like young adult fantasy novels. It made me think of a lot of other books because I read a lot, but it has its differences, I loved it and I can’t wait to read the following books.
