On the night of her claiming ceremony, Scarlett Hart is publicly rejected by her fated mate—Caden Voss, the cold and ruthless Alpha of the strongest pack in the country. Broken and branded a rogue, she runs into the territory of Kael Blackwood, the infamous warlord Alpha no wolf dares cross. But Kael doesn't turn her away. He senses something the packs have hunted for generations: the mark of the Moon Blessed. A human cult, the Hollow, and their silver-tipped hunters want her for an ancient ritual. Two alphas will burn their borders to the ground fighting over who gets to keep her. And the mate who once cast her out now swears he will claim her again. Scarlett Hart was rejected as nothing. She will rise as the key that changes the werewolf world—or the door that breaks it open.
