Blood Moon: Sister Wolf

Isabella Grey is the human foster sister whom Silvermoon Alpha Cain Grey brought back from a massacre eighteen years ago. She grows up under Cain's absolute possession and the restrictions of ancient werewolf law. When priestess Serena challenges Cain's rule and a rival pack invades, the half-wolf bloodline awakened by years of consuming Cain's blood finally emerges. As the truth about Isabella's father and the massacre is revealed, she grows from a captive human into a half-wolf queen.
