Finally finished my re-read of Book #3 of the Mortal Instruments. <snip> Now time to read Book #4 for the first time. Yay!
Hi yoghurtelf, just a heads up on this: I've heard a YouTube reviewer say it's best to read the first book in the Infernal Devices series before Book 4 in the Mortal Instruments series IF you're planning to read ID, and to continue reading them in the order they were published (i.e. Book 2 in ID before Book 5 in MI - if I recall correctly) because otherwise there are spoilers for ID. Maybe someone here can confirm that?
Secondly, you may want to revise your post as it's kind of spoilery, I think. I hadn't read the first three books in MI until this summer, so some of us still need to go through that reveal for the first time.
