The world had ended... When? I wasn't sure, no one was sure. Except them - the beasts, the cause of our demise. The remaining human population has sought shelter from the wolves underground, or that is, those who had not been enslaved and captured. Anelise was one of those humans who, together with her younger sister, struggled for survival and refugee from the beasts. Many say that death is the worst thing which could ever happen to oneself. But we knew better. The worst thing which could ever happen to oneself? being mated to a beast.
