From one of the genre's finest writers comes a bold new epic fantasy in which science and magic are locked in a deadly struggle.
It is the dawn of a new age... The Industrial Revolution has begun, factories are springing up across the country, and new technologies are transforming in the cities. But the old ways do not die easy.
Cat and Bee are part of this revolution. Young women at college, learning of the science that will shape their future and ignorant of the magics that rule their families. But all of that will change when the Cold Mages come for Cat. New dangers lurk around every corner and hidden threats menace her every move. If blood can't be trusted, who can you trust?
