Lyra Thorn survived the impossible: three years in a cursed forest after her mate, Alpha Kallian, shattered her soul with a public rejection. She returned not as the gentle healer who once served the Silverfang Pack, but as something far more dangerous: a woman who commands the balance between life and death. When a mysterious curse begins draining the pack's strength, Kallian does the unthinkable, he begs for her help. The same man who called her "too fragile" now kneels at her feet, desperate and broken. Lyra wants to watch him suffer. She wants to let his pack crumble into ash. But the mate bond she thought was severed still burns beneath her skin, and the curse threatening Silverfang isn't what it seems. As Lyra digs deeper, she uncovers a horrifying truth: Kallian's rejection wasn't his choice. He was manipulated by a force that wanted her destroyed. Now, the forbidden power she wields is the only thing keeping them both alive, and it's killing her from the inside. Enemies emerge from the shadows. Loyalties fracture. And Lyra must decide: Will she save the Alpha who broke her heart, or let the bond between them burn them both to ashes? Because in this game of love and vengeance, the Moon Goddess always collects her debts.
