A fallen queen. A ruthless captor. A realm bleeding into shadow. Queen Seraphine has lost her throne, her army, and the kingdom she once swore to protect. Captured by the feared shadow-knight Lord Kael, she expects imprisonment, betrayal, or death. But Kael does not want her dead. Beneath the ruined heart of the realm, an ancient power is waking. The moon is fractured, the land is cracking, and something older than any crown is feeding on the kingdom’s last light. Seraphine and Kael should be enemies, yet survival forces them into a dangerous alliance built on secrets, mistrust, and a bond neither of them is ready to name. To save a dying realm, a fallen queen must decide whether to trust the man who helped destroy her world—or become the final heir to its darkness.
