17th Century Italy is not as you know it. Sure, it is still serene with beautiful countrysides and wine accompanied by sweet music but lurking in the shadows are vicious monsters known by the locals as Mostri. Mostri terrorise Europe only being able to be subdued by a pair of Musiciste from the Società di Uccisore. For Therese and Tyler, childhood friends, music is the blood that flows through their veins, connecting them to everyone around them. They want to join the Società di Uccisore but never had what they were looking for so they settled for being the town's bards. Singing and dancing, keeping the small Mostri at bay with the sound of song. Its only when the local Spring Fair is attacked by a powerful Mostro, are Therese and Tyler made to flee, but they were made for more and they would become so much more.
