Taken by the Beast

This is the story of two scarred souls. One tormented by suffering and abuse, the other torn with memories of another life and revenge.
In the world they live, one rule and the other is ruled. Submission and endurance are the only ways for the humans, or lowers- how they are called.
What will happen when the thirst of revenge is the only thing that's left to live for? What will happen when the two souls will meet halfway through their dried tears and silenced screams?
Will they mend one another, or will the darkness swallow them?
