Sierra, a skilled human Venator huntress, is traded by her father to the Shadowmoon werewolf pack as a peace offering between humans and lycans. Two rival wolf Alphas, stern cold Caleb and scheming gentle-faced Cain, both claim her as their bride. Locked in a stone cell, Sierra discovers mysterious silver moonblood flowing inside her veins, a forgotten ancient power tied to the Moon’s Covenant that makes her the destined bridge between humans and wolves. The pack’s priestess Selene fears Sierra’s unique blood will break pure wolf bloodlines and repeatedly tortures her to kill her. When a full moon ritual triggers Sierra’s dormant lunar magic, she gains command over moonlight and exposes Selene’s forged sacred texts meant to eliminate her. Sierra strips the priestess of her authority, forces the conflicting twin Alphas to submit to the Moon’s will, and takes charge of the pack’s affairs. She abandons the identity of a traded bride or weapon, stepping into her destined role as the impartial lunar ruler balancing two races.
