For centuries the worlds between Mundane and Supernatural have clashed and resulted in war. Families and friends have been torn apart, countless mundane and supernatural alike have been brutally slaughtered, and the war was never ending. The true culprits behind the war is none other than the Hunter Assassin Association. Zarina and Adele Melbourne are two sisters who are the last sole survivors of their people, after witnessing the brutal attack and slaughter of their pack. The sisters flee in hopes of survival and are soon hunted and tracked down by the H.A.A. The Melbourne sisters must now fully depend on one another and their instincts if their are to survive and stay alive. There are four rules the Melbourne sisters live by: 1) Always trust your instincts. 2) Always fight for survival. 3) Always fight for Freedom. 4) Never Surrender. No matter the circumstances.
