The first novel in a new Cold War fantasy series, where the Berlin Wall is made entirely of magic. When a breach unexpectedly appears in the wall, spies from both sides swarm to the city as World War III threatens to spark. After the war, the wall brought an uneasy peace. When Soviet magicians conjured an arcane Wall to blockade occupied Berlin, the world was outraged, but let it stand for the sake of peace. Now after ten years of fighting with spies instead of spells, the CIA has discovered the unthinkable. The wall is failing. While refugees and soldiers mass along the border, operatives from East and West converge on the most dangerous city in the world to stop the crisis or take advantage of it. Karen, a young magician with the American Office of Magical Research and Deployment, is sent to investigate the breach in the Wall and see if it can be fixed. Instead she will discover that the truth is elusive in this divided city, and that even magic itself has its own agenda. The truth of the wall is about to be revealed.
