Twin sisters were separated at birth: Sera grew up spoiled and selfish, while Eira was lost to the streets. When an arranged marriage looms, Sera refuses to wed Kane Wolfe, a rumored sickly young Alpha, and secretly forces Eira to take her place. Eira expects a miserable year of widowhood—but discovers Kane is only pretending to be ill. Deeply cunning and fiercely devoted, he is the true Wolf King. Eira, gifted with rare flame sorcery, navigates deadly conspiracies, power struggles, and dark witch sacrifices. As she grows stronger, Kane sheds his disguise to protect her. Their fake marriage becomes a bond of mutual salvation. When their twin identity is revealed, Sera spirals into jealousy, allies with dark forces, and launches a brutal rebellion. In the final battle, Eira unleashes her purifying flame to shatter the ancient god’s sacrifice, while Kane awakens the sacred fire of the Alpha. Love triumphs over blood feud and betrayal. Eira rises from a humble stand-in to the head of two great families, and together with Kane, she welcomes twin heirs—sealing an eternal, unbreakable vow.
