In the final installment of Cassandra Clare's The Mortal Instruments series, Clary, Jace, and their friends have to face the demon-brother of Clary, Jonathan "Sebastian" Morgenstern. The whole book is a whirlwind from the beginning, where it starts with young Emma Carstairs in the Los Angeles Institute. She and her friend, Julian Blackthorn, have to escape the Institute whilist carrying Julian's siblings because Sebastian had broken in as part of his plot to destroy all shadowhunters and make them Endarkened warriors. Clary and her friends must travel to Edom--a.k.a Hell--in order to kill Sebastian, but can they make it out alive?

     I recommend this book to all fantasy-meets-the-real-world lovers. The shadowhunter world is as fantastic as it is dangerous, which makes for an exciting story. I think this book is for more mature teenagers and young adults. It contains sexual content, swearing, slight drug use, and bloody massacre. The writing is vivid and imaginative and could leave chills down your spine at some parts and make your heart swell with the romance of others. Clare's writing is imaginative and amazing, and I loved it overall.

     Cassandra Clare's books seem to be more towards older teenagers and young adults. Her vocabulary in the novel is definitely not at an elementary or even a middle school level. She includes Latin phrases as well (which are, luckily, translated). As aforementioned, the mature content in this book and the book before this one was more than in any of the other books in the series. But said content only adds to the angsty-teens-saving-the-world aspect.

     Clare's writing makes you want to laugh, cry, and throw the book across the room (I did all three). Maybe I just did those things because I get attatched to characters easily, but tears were shed. I think the book's soul purpose was not just to finish off the series, but to also make her fangirls (and boys) cry and want more. She's happy to deliver more heart-wrenching books with her new series, The Dark Artificies. I am sad to see this series end but I think that's the sign of a good series. The end will leave you staring at the page and thinking, "Well, I don't know what to do now that this is over."

     City of Heavenly Fire is about seven not-so-normal teenagers who have to save the mundanes--or humans--from Sebastian Morgenstern. Sebastian has teamed up with the Seelie Queen, the ruler of the faerie race, against the shadowhunters. Sebastian wages war by turning shadowhunters into Endarkened shadowhunters, giving him control over them. Meanwhile, Jace is filled with burning Heavenly Fire that could possibly kill Sebastian, if only he knew how to control it. The Heavenly Fire also prevents Jace from getting Close to his girlfriend, Clary. But when the ambassadors of the five races--faerie, shadowhunter, werewolf, vampire, and warlock--are kidnapped by Sebastian, Clary, Jace, Simon, Isabelle, and Alec must go to his palace in Edom to save them.

     I loved this book! I thought it was better than the others in the series, but it didn't beat The Infernal Devices for my favorite series by Cassandra Clare. The book is relatable in the teen aspect. Jace's snarky comments and Alec's new-found sassiness only added to the reliability. Thank goodness for the comic relief of Jace, Alec, and Simon. All in all, I would recommend this book to all my friends and family if I haven't already.
