I cannot put all of my Clockwork Princess feelings into a non-spoiler review very easily and would really like to go into a lot of detail so I've decided to write a spoiler review for this amazing book. I may try and write a quick review some other time but, for now, this is my Clockwork Princess review. I will be talking about all three books in the trilogy so if you haven't read them then please don't click the 'Read More' button.Cassandra Clare ripped my heart out and then stitched it back up. But, just like if you smash a piece of glass, there are some tiny shards missing that will never be replaced. At the end of Clockwork Prince, I was full of despair. Although I never concluded which 'team' I was on, I wanted Tessa to be with both Will and Jem because I loved them both. This is one of the things I love most about the love triangle in this book; the reader feels exactly the same as Tessa. With Jem proposing to Tessa, I knew that she wouldn't want to hurt his feelings even though what she was feeling for Will wasn't normal. I also knew that, if Jem were to die, Will would never want to be with Tessa. Will actually said, when conversing with Magnus Bane: “If Jem dies, I cannot be with Tessa,” said Will. “Because it will be as if I were waiting for him to die, or took some joy in his death, if it let me have her. And I will not be that person. I will not profit from his death. So he must live.” He lowered his arm, his sleeve bloody. “It is the only way any of this can ever mean anything. Otherwise it is only —”So I was left wondering how this beautiful trilogy could ever end in a way that would satisfy readers and I'm pleased to report that I thought it was amazingly well rounded off.I was a little wary at the start- four pages in and we'd already witnessed a death! It was clear to me that, even though she was dead, Adele Starkweather would play a big part in this novel.The other part of the prologue shows Will and Jem's first meeting and I was really pleased to see this. It wasn't something I thought we would ever be able to read and yet it shows us something about Will and Jem's relationship that is vital to the readers understanding of them. I was a little shocked at the things Will came out with in the scene but then he thought he was cursed at the time so I couldn't really blame him.The first chapter was full of witticisms that I have come to recognise from Cassandra Clare and I particularly loved the scene which I like to refer to as the 'Lightworm Incident.' Here are a few quotes from that scene:“And indeed it was, the arrow still protruding from its wet, grayish skin, humping its body along with incredible speed. A flick of its tail caught the edge of a statue, sending it flying into the dry ornamental pool, where it shattered into dust.“By the Angel, it just crushed Sophocles,” noted Will. “Has no one respect for the classics these days?”“Gabriel’s green eyes sought Will. “It was demon pox, wasn’t it? You know all about it, don’t you? Aren’t you some sort of expert?”“Well, you needn’t act as if I invented it,” said Will.”There are various mentions throughout the book of Benedict Lightwood as the 'Lightworm' and I don't think I'll ever be able to see a worm without thinking of Clockwork Princess again.There was also some brilliant relationships between characters, excluding our main one. I loved the interaction between Gabriel and Cecily, who we saw a lot of in this novel. Cecily was a female replica of her brother and I'm hoping that we'll get to see more of her in Clare's future novels, so far named TLH, concentrating on the second generation of Shadowhunters.Sophie and Gideon were also very sweet together and I was really pleased that Sophie got to Ascend because I wasn't exactly sure of what the process would entail and so it was brilliant world building.The way in which Clare has weaved all of her books is amazing and she is an author that I idolise for this reason.Now, I've noticed that this review is getting rather long so I'll start talking about the epilogue now. I had no idea that it would end in the way it did but I was surprisingly pleased. I was very upset, though. The main reason for this was because we, the reader, witnessed Will's death and, even writing this now, it saddens me. I was pleased that, eighty years later, Jem and Tessa met on Blackfriar's Bridge and got back together because Tessa truly did love both Jem and Will. I don't think Will would be upset with this because, at the end of the day, he was willing to let Jem and Tessa get married when he was alive. He cares for them both, just as Tessa cares for Will and Jem and Jem cares for Will and Tessa.But this still isn't over! Even though Clockwork Princess is the last book in the Infernal Devices trilogy, we still don't know how Jem was released from the Silent Brothers and why. I can't wait to read City of Heavenly Fire to find out.
