The Infernal Devices is a prequel series to The Mortal Instruments and is set in Victorian London. It consists of three books: Clockwork Angel, Clockwork Prince and Clockwork Princess. I read these books on 12/05/14, 13/05/14 and 14/05/14.
The main characters are all ancestors of the main cast from TMI, Herondales, Lightwoods, Fairchilds, Carstairs (which we will learn more about in The Dark Artifices) and a few other important Shadowhunter families. The three main characters are Tessa Gray, Will Herondale and Jem Carstairs, who are kind of involved in a weird love triangle but without the arguments and jealously. I don’t know how Cassandra Clare managed to write a love triangle that was quite balanced, but she did. I found myself routing for both Will and Jem equally, which was nice for a change.
Without spoiling too much of the plot for people who haven’t yet read these books, I’ll just do a basic synopsis:
Tessa Gray travels to London from America to live with her brother, but when she arrives she is abducted by two creepy sisters who keep her locked up. Here she learns she is not quite normal. After a weird series of events she ends up living at the London Institute, ran by the Fairchilds, where she meets the Shadowhunters and learns the truth about their world. She realises she is involved in a huge scheme involving downworlders, clockwork people and demons, and has to use her new-found powers to help save the people she loves.
I actually think I enjoyed this series more than The Mortal Instruments, mainly because the Victorian setting was great, they’re in Wales for part of the series (woo, Wales) which is nice to see in any book, and the relationships between the characters were played out really well. It’s not necessary to read both series, as you can enjoy them individually, but the upside is that you know more about the characters backgrounds, like Magnus, for instance.
So, overview: badass female protagonist, cute half-Welsh love interest, cute half-Japanese love interest, lots of fight scenes, twists, clockwork creatures, Magnus Bane, Wales, and ancestry.
