Sebastian Morgenstern is on the move, systematically turning Shadowhunter against Shadowhunter. Bearing the Infernal Cup, he transforms Shadowhunters into creatures out of nightmare, tearing apart families and lovers as the ranks of his Endarkened army swell.
The embattled Shadowhunters withdraw to Idris - but not even the famed demon towers of Alicante can keep Sebastian at bay. And with the Nephilim trapped in Idris, who will guard the world against demons?
When one of the greatest betrayals the Nephilim have ever known is revealed, Clary, Jace, Isabelle, Simon, and Alec must flee - even if their journey takes them deep into the demon realms, where no Shadowhunter has set foot before, and from which no human being has ever returned...
Love will be sacrificed and lives lost in the terrible battle for the fate of the word in the thrilling final installment of the classic urban fantasy series The Mortal Instruments!
So, it's over. I'm actually glad that this series has finally ended. It was time. At first when Clare extended this series by 3 extra books, I didn't see how there was any story left. The Mortal Instruments had ended. I think she did a fairly good job of creating new issues, and I think I might have enjoyed the second half of this story more than the first. There was a lot more action, albeit it was a lot darker than the first 3.
In this book the loose ends are tied up, although, after I finished I was left with a feeling, of "That was it?" I expected more and was slightly disappointed, although I think the ending suited the story.
In reality, the Shadowhunter story isn't over though. Clare has a whole new series set to debut in March and who knows how many other books with this theme she'll go on to write. I'm not complaining, at the moment at least, because if she writes them, I'll gladly read them.
