In Frost Valley, Rowan Ash is an unregistered outcast who cannot awaken even the lowest C-rank bloodline, making him the clan’s favorite target for ridicule. Only Princess Selena and the mysterious spirit Fenric Blackmane believe there is more to him than the Bloodline Stone can measure. When Selena’s royal bloodline violently backfires and the elders plan to force her into a marriage bond with the highest A-rank wolf, Rowan makes a deadly seven-day oath: he will enter the forbidden Northern Sacred Mountain and return with the legendary Moonfrost Flower, or die.
Against blizzards, betrayal, assassins, and a ticking blood bell, Rowan fights his way back in time to save Selena. But his return triggers an even greater reckoning. His hidden black-gold power awakens, Fenric makes one final sacrifice, and the conspiracy behind the forced bond, secret attacks, and forbidden drugs is exposed. The wolf everyone called worthless is finally strong enough to challenge the rules that condemned him—and give Selena the right to choose her own fate.
