Charlie's the kind of boy that no one notices. Hell, his own mother can't remember his name. So when a mysterious clockwork man tries to kill him in modern day Philadelphia, and they tumble through a hole into 1725 London, Charlie realizes even the laws of time don't take him seriously. Still, this isn't all bad. Who needs school when you can learn about history first hand, like from Ben Franklin himself. And there's this girl... Yvaine... another time traveler. All good. Except for the rules: boys only travel into the past and girls only into the future.
Even as the modern world pushes the supernatural aside in favor of science and steel, the old ways remain. God, demon, monster, and sorcerer alike plot to regain what was theirs. 1913, Salem, Massachusetts - Sarah Engelmann's life is full of friends, books, and avoiding the pressure to choose a husband, until an ominous vision and the haunting call of an otherworldly trumpet shake her.
