The first book in a new dark, seductive and all-consuming fantasy series, in which a human commander and the masked enemy interrogator sent to break her are drawn into a slow-burn, dangerous bond - one that could end a fifteen-year war or ignite something far deadlier. Perfect for fans of Alchemised and Samantha Shannon. Vordell was beautiful once. Its people lived in harmony, and their civilization flourished as they learned to harness and control the power of Light. Then the darkness came. The Iron Sky unfolded dark clouds across the land, thick enough to choke out the light of the suns. The ground cracked, releasing vicious creatures that looked like humanity’s oldest fears. The Dar’rak - an enemy long believed to be buried and forgotten - returned to claim the world above. Soraya Tollmere has spent most of her life on the front lines of the brutal war that followed. Now a high-ranking commander, she knows loss better than anyone. By day, she leads troops across ruined landscapes and guides covert teams through enemy territory. By night, she meets with a Dar’rak defector who has kept humanity alive with his steady stream of secrets. On a mission to investigate his latest lead - one that could turn the tide of the war - Soraya is captured by The Demon, the Dar’rak’s most feared soldier. His orders are simple: break the human commander, uncover where the humans are keeping a weapon that could win them the war, and bring it to the Dar’rak. But as he gets to know the fierce warrior, the lines between interrogator and enemy, prisoner and ally, begin to blur. As devastating truths surface and loyalties shatter, Soraya must decide who to trust in a world where light is dying - and where her greatest enemy may be her only salvation.
