Sofia and Medea led rival sects (the Akousmatikoi and Mathematikoi) in the vampyr nation, engaged in a cold war across centuries. The last thing standing in the way of open conflict is swept away and suddenly, bloodshed is the new normal. Unfortunately, someone wants them dead even more than they want to murder each other. As the Romanian revolution rages, they're both stunned as a mysterious force called The Reaper slices through Mathematikoi and Akousmatikoi alike using ancient weapons and an uncanny gift for killing immortals. Can they find a way to work together before it's too late?
We see the heads of the 2 vampire nations fighting and it is against each other - but now an enemy has surfaced. This enemy is threatening them all. We see different personalities emerging with the 2 main vampire characters. I like that I am not sure where this series is going. Do we see a surprise ending?
