Bound to the Alpha King. The Alpha Mates Series, #3

They were forged in hatred. Bound by magic. And now, one must die to save their world. In the ancient realm of Vorthak, the mystical Lunar Courts have ruled for millennia. But now, a deadly curse is unraveling the very core of shifter magic, threatening to bring all packs to extinction. The only solution lies in a forbidden blood-binding ritual between two sworn enemies. Kyreth Shadowmere, the ruthless Alpha King of the Obsidian Pack, has spent years consolidating power through conquest and fear.
His last war left Aethermoon, a city of celestial magic-in ruins. The only survivor? Zephyra Nightwhisper, a rare Stellarcaster and elite dimensional assassin who's spent seven years hunting him in silence. But when a cosmic horror, an ancient Void entity, begins devouring shifter souls across every territory, Zephyra is faced with a devastating truth: the only way to stop it is by bonding with the very Alpha who destroyed her home.
Their blood-binding doesn't just tie their lives, it weaves their memories, emotions, and deepest fears into one consciousness. As Kyreth and Zephyra fight side by side, what begins as raw hatred morphs into reluctant understanding... and then into a connection neither of them dares name. Together, they uncover a secret: the centuries-old war that made them enemies was orchestrated by the Void itself to fracture the Lunar Courts and weaken the realm's magical defenses.
But the ritual to defeat the Void comes with a cruel cost: one of them must die to complete it. With time running out and their bond deepening into something neither expected, Kyreth and Zephyra must decide-can love rewrite fate, or is one destined to be the sacrifice that saves them all?For fans of: Fated mates with forbidden magic Star-powered shifters and ruthless alphas Cosmic enemies and ancient curses Emotionally charged enemies to lovers Dark fantasy romance with high stakes
