The Wolf: The Prequel Publisher's Summary
Before the legend of the Keepers, came the story of the Wolf.
Once upon a time, there lived a man whose fate would rest with two sisters. One will hold his heart. With her, he will find a love that will last forever, though it will come with a price.
From the other sister, he will learn fortitude as he discovers that she holds the power to destroy all he holds dear. For as easily as one sister captures his heart, the other will trap his soul.
