Luna Cassian survived a rogue attack, a stillborn daughter, and eight months of her Alpha mate's growing distance—but the silver poison coursing through her veins isn't what's killing her. The mate bond she's been systematically severing in secret finally snaps the night she walks into the pack clinic bleeding and numb, and Alpha Thorne feels the loss like a knife to the chest. Too late, he realizes the wife he took for granted has gone cold, her jealousy buried alongside the child she mourned alone. Now he'll do anything to reclaim what he destroyed, but Cassian has already paid the price for loving him. And when she discovers the truth about who he's been meeting in the shadows, even the remnants of their bond won't survive what comes next.
