Subtraction: Book 4 of 5
With their true enemy revealed as their old teacher Pythagoras, Akousmatikoi leader Sofia and Medea, head of the rival Mathematikoi, try to find a safe haven. He spent years using his powerful gift of mesmerism to create a network of disposable sleeper agents around the world, allowing him to keep an eye on his former students and stymie their efforts on a global scale.
Unwilling to task the significantly more fragile human lives against the threat of vampyrism, Pythagoras travels constantly, moving from threat to threat and always keeping a vast mathematical model of the vampyr nation in his head, to track his quest to its completion. How will he address the challenge of finding his prey when they are trying to hide?
