The fae have magic.
The humans have machines.
Neither has mercy.

The war against the fae stole Zari’s future. Now she works as a nurse, dedicating her life to healing those still recovering after the final battle.

When a mysterious fae mage appears, claiming her long-lost father is imprisoned by the fae, she strikes a dangerous bargain. Zari will infiltrate the fae Queen’s court, posing as one of her magical Oathborn soldiers, for a chance to bring her father home. But if she’s caught, her life, and the fragile peace, will be forfeit.

Pursued by enemies on both sides, haunted by the past, and drawn to a man she cannot trust, Zari must decide what she’s willing to sacrifice and who she’s willing to become. Because to the fae, Oaths aren’t just binding, they’re deadly.

A thrilling start to a new romantic fantasy series, perfect for fans of One Dark Window, Swordheart, and Once Upon a Broken Heart.
