Summary (from Goodreads): The Infernal Devices is a series of prequels to The Mortal Instruments series, set in 19’th century London. The story concerns 16-year-old orphan Tessa Gray, whose quiet life is thrown into turmoil when her older brother Nathaniel suddenly vanishes, leaving her alone. Her search for him leads her into Victorian-era London’s dangerous supernatural underworld, where warlocks throw masked balls for half-demon Downworlders. When Tessa discovers that she herself is a Downworlder, she must come to trust her natural enemies, the demon-killing Shadowhunters, if she ever wants to learn to control her powers and find her brother. Torn between the beautiful Will, a Shadowhunter who isn’t what he seems, and the devoted Jem, whose own deadly secret is slowly destroying him, Tessa must draw on all her strength to save her brother and keep herself alive in this deadly new world.
Why I want to read it: I love all books by Cassandra Clare, and I love the fact that this series set in the 19th century!
