England, 1888. The trees are green, the birds are singing, and in 200 years demons will destroy it all. Unless Joan, a rough-around-the-edges assassin from the future, can take out the dark magician responsible. But to get close to her target she'll need help learning how to fit into society.
Simon has his own reasons for wanting to destroy Alex Reynell, and Joan may be his perfect revenge. But as each day passes, Simon is less sure he wants her anywhere near Reynell. Because no spell in the world will save his future if she isn't in it.
