She was born without the sacred crescent mark that crowns the worthy. Reduced to shadows and servitude, Ashley Voss has spent her life protecting the only soul who ever showed her kindness: her half-sister Clara, the perfect Luna-to-be. But when the dangerously magnetic heir Damien Blackwood coldly declares his plan to impregnate Ashley in a ritual claiming and then discard her to preserve Clara's purity, something ancient awakens. One stolen glance ignites an impossible true mate bond, a feral hunger neither can deny. Caught between loyalty to her sister, her father's wrath, and a desire that could shatter empires, Ashley must choose: safeguard the sister who deserves the crown or surrender to the brutal alpha who was never meant to crave the unmarked girl. One night of raw, desperate passion. One forbidden bite. And a deadly dawn duel where love will either rise victorious or bleed out on frozen ground.
