The final battle approaches! Question Zero: answer it correctly, and your quest will be fulfilled. Answer incorrectly, and your head will be removed. The human Amir Tarkos and his bear-like partner Bria are members of the elite Predator Corp, the only military force capable of defeating the dangerous Ulltrians. If they can locate where the Ulltrians have hidden their fleet, they can take the war to the enemy. But the answer lies on the Shroudworld, where rebels from throughout the galaxy have gathered to use mathematics as a weapon. And they want to claim the heads of Tarkos and Bria. In a thinking labyrinth, when everyone betrays them, Tarkos and Bria have only each other, and their own cunning, to aid them. Can they defeat the most subtle enemies they have ever faced, in a struggle of logic and deception? QUESTION ZERO Novel 55,000 words LEARN MORE: BOOKS IN THE PREDATOR SPACE CHRONICLES: 1.
