Clockwork Angel, by Cassandra Clare from Best Young Adult Books of All Time

What it's about: It's 1878, and Tessa Gray is searching through London's seedy, supernatural underworld for signs of her missing brother. When she finds the demon-slaying Shadowhunters as her only allies, the team sets out to undermine the Pandemonium Club — a dangerous group of vampires, warlocks, humans, and demons planning to rule the empire. Top quote: "'One must always be careful of books,' said Tessa, 'and what is inside them, for words have the power to change us.'" Goodreads rating: 4.32/5
