A thousand years ago, the Angel Raziel mixed his blood with the blood of men and created the race of the Nephilim. Human-angel hybrids, they walk among us, unseen but ever-present, our invisible protectors.
They call themselves Shadowhunters.
The Shadowhunters obey the laws set down in the Gray Book, given to them by the angel: their mandate is to protect our world from the interdimensional parasites they call demons, who travel from world to world, razing and destroying everything in their path. Theirs is also the task of keeping the peace among the warring Downworlders: the human-demon crossbreeds we know as warlocks, vampires, werewolves, and faeries. Though the Shadowhunters hail from their own secret homeland, the country of Idris, they keep outposts in each of the major cities of the world: New York, Tokyo, Shanghai, Paris, St. Petersburg — and London.
The year is 1878. A killer stalks the dark streets of London, flaying his victims alive and removing their skin, leaving behind the stench of demonic witchcraft wherever he strikes. Seeking his identity, the Shadowhunters of the London Insitute find one clue: a membership badge for a secret organization called The Pandemonium Club. Some of London's richest and most successful men are members. But which of them is the killer, and what is his ultimate goal?
Meanwhile, sixteen-year-old Tessa Gray's search for her missing brother — once a member of the Pandemonium Club — leads her into Victorian-era London's dangerous supernatural underworld, where vampires stalk the gaslit streets of London, werewolves slink in the shadowy lanes of Whitechapel, and warlocks hold masquerade balls for demons and Downworlders in opium-smoke-filled ballrooms. When Tessa discovers that she herself is a Downworlder, she must learn 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 beautiful Will, a Shadowhunter hiding his true nature, 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.
