The Infernal Devices = A Tale of Two Cities???

This post may contain spoilers.

Okay, so I was reading "Clockwork Prince", a book from the series, "The Infernal Devices" because I could not sleep (obviously from what time it is). Earlier, I read this for my English I assignment about the difference between good and bad writing which I both took from the said book. I just continued where I left off. Then I noticed that in the beginning of the book, a quote from Charles Dickens' "A Tale of Two Cities" was stated. I remember encountering the same book over and over again from the first book of the series, Clockwork Angel (the book connected the two main characters). Because of that, I decided to Google it up.

I have tried this before in the first book, but did not make much connection. But because of the marriage between Jem and Tessa, I realized that the story may end up like ATOTC!!! >< However, as I wrote this post, it dawned upon me that the marriage may not come fort and Will may be the one who will marry Tessa. Or maybe, the author will make a twist and do the exact opposite of what my first conclusion was - that even though Jem and Tessa will get married, Jem may be the one who will sacrifice his love for Tessa. This is gonna make my head explode and I am seriously looking forward to a happy ending (so that Jem will be mine :))) but that will never happen in real life T.T ) I am really looking forward to the conclusion of this story! >< I hope that the author won't blow it with a crappy ending ><

PS: The Mortal Instruments Series should have been left off. Six books are way too many for a readers' interest - but that is only my opinion :D.
