Welcome to London 1899. With hot gossip, scandalous hook-ups, twirling dresses and Demons. Vampires, werewolves and fairies, all myth right? Wrong. London’s society is unaware of what goes bump in the night. What matters to them is to know the latest fashion and throw the better party. But vampires, werewolves and fairies, aren’t they’re worst problems. Demons evade the streets of London. The only thing standing between them and the innocents are the Shadowhunters. Nephilim sworn to rid demons of the earth, they are the ones who protect society. In London 1899, young Angelica Fairchild, is but another shadowhunter. Fighting demons comes easy to her, dancing not so much. But when trouble stirs the streets of London, her brother William, James Morgenstern, Samuel Lightwood and her, are the only ones who can stop the madness. Dark secrets reveal themselves in the time of innocence, that’s not as innocent as it seems. Betrayals and secrets intertwined in their fates. Something big is going to happen, something world ending, and it’s not just the dawn of the new century.
