Shift, fight, survive. Those are the rules of The Ring. Two wolves enter, one wolf leaves.
Rukiya Moonborn is a slave, a werewolf whose master forces her and many others to fight to the death for the entertainment of the wealthy. Named "Dogs" after the lesser beasts, wolves like Rook live short, violent lives.
The masters dangle the illusion of hope in front of the Dogs by insisting any wolf who survives 100 fights in The Ring can win his or her freedom. Rook is on her 18th fight against the West Coast Champion - the biggest she-wolf anyone has ever seen. As if this weren't enough, Rook finds a wolf pup who is destined for slavery as a Dog and helps the child escape the master's clutches - a crime easily punishable by death.
When Ryker - the master's handsome right hand - catches her in the act, Rook embarks on a journey that will be the ultimate test of her courage and strength.
