Irrational Numbers: Subtraction Book 1 of 5

Once, Zalmoxis was a slave taken in by Pythagoras, one of the greatest minds of his era. Pythagoras freed Zalmoxis, made him an apprentice and took him around the world. Zalmoxis gained knowledge, love and respect. To repay his master, he sought ancient wisdom to mix ancient legacies into a new kind of monster: the vampyr. The year is 1948, and centuries after his master rejected everything, Zalmoxis stands between two vampyr tribes warring through the eras -- his Dacian countrywoman Sofia's Akousmatikoi and the Mathematikoi run by the former priestess of Hecate named Medea. Can he pull the broken vampyr nation together to stop a threat to everything they've built?
