At her side are the immortal warriors of The Righteous—among them her husband, her lover, her soul-mate Michael. With a passion bordering on possession, Cin's love for Michael knows no bounds. But when a ruthless plantation owner kidnaps Cin's cousin, the most terrifying battle of all awaits. Cin is drawn to the irresistible lure of dark magic to stop their enemies, while Michael staunchly opposes it—putting their love and loyalty to the ultimate test.
