Eira Thornwind has spent four years hiding the most dangerous secret in the shifter world—her wolf, Veyla, awakened at fourteen, two years earlier than any shifter in recorded history. Ancient, powerful, and carrying memories that don’t belong to this age, Veyla marks Eira as a prize any alpha would wage war to claim. Only her parents and a pair of trusted elders know the truth, and they intend to keep it that way. Now, with Eira’s eighteenth birthday approaching—the age when shifters can finally sense their fated mate—the annual Summit of the High Packs arrives on Crescent Fang land. Politics, competition, and centuries-old grudges simmer beneath the surface. Among the visiting delegations is Kalen Draven, the newly risen Alpha of the Ironshade Pack. Ruthless. Respected. Scarred by a past that forged him into a weapon. He expects manipulation, strategy, and power plays. He does not expect the Alpha’s daughter to strike him like a bolt of silver fire. Eira wants nothing to do with him. She doesn’t trust the cold Alpha with predator’s eyes, and she certainly doesn’t trust the way her ancient wolf stirs whenever he enters a room. Their packs are enemies. Their futures are already tangled with responsibility. But fate has its own design. Something old stirs beneath their feet. And a bond forged in silver flames may be the only thing that can save—or destroy—the shifter world. A slow-burn, enemies-to-lovers shifter romance filled with prophecy, danger, forbidden power, and a connection neither of them is ready for.

For a thousand years, the city of Crescent Falls has survived beneath the shadow of an ancient savior. Each century, a man is chosen as an offering to Sariyah—the being said to have once driven demons from the world. When Bastion, the man Ember loves, is taken after daring to refuse her, Ember’s grief turns into defiance, and she vows to bring him home no matter the cost. Her search forces her into an uneasy alliance with Orion St. James, a dangerously charming immortal with a violent past and secrets tied to Sariyah herself. Bound together by a magic neither of them wants nor understands, Ember and Orion are drawn into a hidden war beneath the city—one involving cultists, monsters, and an ancient order known as the Watchers. As Crescent Falls begins to fracture, Ember experiences unsettling visions that hint her bloodline is far more entangled with Sariyah than anyone ever suspected. Strange new powers awaken within her, blurring the line between protector and destroyer, while enemies gather and old loyalties are tested. With the city on the brink of collapse and unseen forces moving in the shadows, Ember must decide how far she is willing to go to save Bastion—and whether becoming something darker is the only way to stop an evil that has ruled unchallenged for centuries. Because some thrones are not inherited. They are taken.

Kyra should have died the night her world was reduced to ash. Born into a powerful bloodline of fire witches, she watched her family fall—slaughtered by a king terrified of their magic. Scarred by flames and driven by vengeance, she returns to the kingdom years later, disguised beneath another face and hiding in plain sight as a palace servant. Her mission is simple: learn the king’s secrets and, when the time is right, strike. But fate has other plans. Prince Lucian is nothing like his father--- the king. Cursed as a werewolf, he has hidden his dark secret from the royal court for years. The only cure? A witch’s blood—Kyra’s blood. When Lucian meets Kyra, an unexpected bond ignites between them. He should be her greatest enemy, yet fate twists their paths together. For beneath her servant’s disguise, Kyra is no ordinary girl—she is the last of a fire-witch bloodline, bent on avenging her family by killing the king. When Lucian discovers her secret and her deadly mission, he doesn’t condemn her. Instead, he offers to help her, driven by his hatred for his father… and his growing love for her. But as their alliance deepens, a devastating truth emerges: the only way to end Lucian’s curse is through sacrifice—Kyra’s life or his own. Now, Kyra must face an impossible choice: save herself… or the man she loves.
