London, January 1789 The weather is so severe the River Thames completely freezes over. The people of London decide to hold an impromptu Frost Fair, with dancing bears, jugglers and puppet shows. Neva and her Russian parents operate a chess-playing bear, so convincing people believe it is real. But a dreadful tragedy is waiting just around the corner for Neva, as the treacherous ice begins to crack. All of a sudden she finds herself alone in the world, until her fortunes change and she is adopted by eccentric clock and automata maker, Victor Friezland. As Neva grows up, she discovers she has a gift that will prove to be as dangerous as it is desirable: she can predict the weather, and her adoptive father devises a machine to help her. Now Neva, a woman ahead of her time, must find a way to disguise her true identity from those who would destroy her.
