Mortal Instruments Monday; Week 3: Favorite TMI books in Order

Wow, it feels so insane that the book is coming out in only a week. One week. God, the end is coming closer and closer, it feels so weird that we are so close to the end. In preparation for the release of this final book, I came up with Mortal Instruments Monday. Every Monday, a new Mortal Instruments post will come up, and there is a topic that will be discussed for that Monday (or if you are unavailable, you can do it whenever you want in the week). This week, we are talking about our favorite TMI books from least favorite to our absolute favorites, and there has to be a little explanation for why it is in that position. It can be a long description or just a single sentence. I'm sure most of you have already read all 5 of the current books, but I'm still in the process of reading the rest of the TMI series -hides under a rock-.
Anyway, if you are in the same boat I am in, you can give your favorite of how many TMI books you have currently read and apply them to this. So, let's get this started.
