I really enjoyed it. It was nice to see the characters developed through the book and it was more or less easy to follow. A few times I found myself forgetting who some of the background characters were but that's my own fault at this point. The ending wasn't quite as clear as it should have been, but knowing how the game plays out I figured it out okay.
Dracula - Bram Stoker 9/10 (I never thought I'd like it so much)
It - Stephen King 7/10 (I hated the last 200 pages, I liked the way the book was written, but the end ... even King admitted he was high when he wrote that.)
I just finished rereading The Demonata series by Darren Shan; I forgot how much I enjoyed this series, so reading it after so many years reignited that younger me. It was also kinda funny seeing how some of my opinions changed for certain characters. Younger me really had no taste.
Overall (for the whole 10-book series) I give it a 7.5/10. The ending was so-so... quite anti-climatic after all the build-up it had, but the journey was fun with the three main protagonists; reading from three different perspectives made it more interesting for me. Out of the series, Demon Thief, Bec and Demon Apocalypse are probably my favourites.
