Blood Luna

Humans thought werewolves were their only problems. They built their cities in plains away from forests and those that were near packs built walls to protect themselves. But when vampires started taking over small towns and cities humanity realized the wolves were the least of their issues. But none of that mattered, only small cities that didn't have the infrastructure to protect themselves were attacked. A big city like the one Calla lived in was perfectly safe and at no risk of falling, right?
