The Fault in Our Kinds: Book One

There was once a time of peace and harmony between the Monsters and the Divine. They all lived peacefully in the Haven of Mythical Beings, a place far away from the wretched mortals in the human world. Well, that was until the Great Famine. This was a time of hunger, and sadness and despair. Eventually, the food supply began to run low. There was enough food for the people to live healthily for 20 years, enough time for the famine to end, however, one monster or divinity must be removed from the Haven and left to rot and eat human flesh in the mortal world for 20 years until the famine ended.
This is when the Games of Chance began.
There they hosted a series of games to prove to the Haven which kind is the best. There, the Meifwa claimed victory by beating the Zombies in a combat challenge, while the Zombies were sent to exile. 20 years have passed since that day, and most people have assumed that the Zombies have all died out, due to the ruthlessness of the human world. But now things have changed, both for Zombies and the Haven. The new question is: Is it for the better, of the worst?
