The Sword Of Aeldaerin by Prerna Ashok Book 1

Demi-fae. Cursed. Traitor?

Ehva Delmonte is cursed, bound to her cruel stepsister for life. Secrets are unraveled as Ehva digs into her past, hoping for answers and a way to break the curse. When Crown Prince Elric asks her to steal the Sword of Aeldaerin to secure the support of the court, Ehva realizes this may be the key to her freedom. But the high-stakes heist comes with high risks, along with the prince's irritatingly handsome stepbrother, who is determined to thwart Ehva at every step.

She'll do anything for her freedom, but can she commit treason?

Hunter. Warrior. Thief?

Tristan de Tourney is Morovia's fiercest mage hunter. He will do everything in his power to keep his stepbrother, Elric, from destroying the peace his father died to achieve. The only way to maintain that peace is by restoring the long-lost Eye of the Goddess to its rightful place. In order to do so, Tristan must steal the ancient artifact. And the enigmatic demi-fae female might be his only way to do it.

Magic is fading, wards are failing, and thieving is his only option.
