The Omega Who Chose the Rival Pack

She was raised to fear the rival pack. Falling for its Alpha heir could cost her everything. Tamsin Vale has spent years proving that being an Omega does not make her weak. As Silver Moon's gifted Echo-Walker, she can touch ancient bones and experience the memories they carry-but when a long-silent relic suddenly awakens, it shows her something impossible: a pair of amber eyes belonging to a wolf who is still alive.
Across the forbidden border, Corvin Ashgrave, First Enforcer and heir to Iron Veil, is investigating the same disturbing threat. A mysterious gray rot is spreading through the forest, turning healthy land lifeless and driving wolves feral. When Tamsin and Corvin meet, neither expects the powerful recognition that sparks between them. They should be enemies. Their packs have hated each other for generations.
Tamsin still blames Iron Veil for the raid that took her mother, while Corvin carries secrets about that night he has never dared confess. But the deeper they investigate the dying land, the more they uncover a truth both packs have spent a century burying. Their ancient feud may have begun with a forbidden bond that was violently broken-and the connection forming between Tamsin and Corvin may be history attempting to repeat itself.
Their growing mate bond is forbidden by the Accord. Discovery could mean exile, betrayal, or worse. Yet as the rot spreads and old lies begin to unravel, Tamsin faces an impossible choice: remain loyal to the pack that raised her, or trust the rival wolf who may hold the key to saving them all. Because sometimes the greatest act of loyalty is choosing the future everyone else is afraid to claim. This description accurately reflects the manuscript's Echo-Walker heroine, rival-pack hero, spreading supernatural rot, forbidden cross-pack bond, and buried history without revealing the full ending.
