A very fun read. I found this one much better than the last two, and much more exciting. This one also had great character development (I liked all the characters that had previously annoyed me much more in this one) and very satisfying conclusions to, well, everything. 
 I am honestly not sure why there are another three books in the TMI series (well, I have some idea... $cough$$$cough$) and I've heard it's a pretty common opinion that it perhaps should have stayed as just the trilogy it was originally supposed to be, so I may not read the rest of this series but I am looking forward to reading The Infernal Devices trilogy sometime soon.
