I would rate this as 3.5 if I had the option on here.
The book was good, enjoyable, of a similar style to book 1. I liked the addition of Maia as a character and I liked that we got to see more of Luke and that more happened involving Simon. I felt the plot was interesting and obviously helped to progress the characters, but at times I felt that it was stalling a bit unnecessarily to prolong the book, and at times I felt that so much was going on that it was hard to keep track of what was happening or why. The Inquistor storyline seemed rather pointless and irritating to me. Jace still annoys me greatly.
