I just finished reading The Mortal Instruments Books 1-4. I have heard that she is due to have 2 more books come out in the series and I am excited for them. City of Bones was a little bit crazy at first because it feels like there is so much going on, but I believe that is her style of reading and by the end I was well informed and ready for the next, City of Ashes. City of Ashes, the humor was wonderful. Usually I don't read books and laugh out loud, but this one I did! City of Glass let me feel like the series was wrapped up pretty good and I wasn't expecting too much from City of Fallen Angels, but City of Fallen Angels focuses more on Simon and has a crazy cliffhanger for an ending! If you are a big reader of Fantasy and nephilium, angels, demons, werewolves, vampires, etc. This series has it all!!
