Teacher's Pet (Darkville High) by Eva DeMoan

Chaos. Pain. Destruction. It's all anyone knew after the rift opened and monsters entered our world. The things of nightmares, horror stories. The beasts that hid in the night. They're all real, and they're here. When my parents moved us to Darkville and enrolled me at Darkville High, I knew I was to be sacrificed for their happiness. Now I have a choice… become the pet of a monster, or be cast out into the world, where survival isn't guaranteed.
