To Crown A Traitor by Katherine MacDonald

A traitor on the run. A prince bound by duty. A love caught between ruin and redemption.

Branded a traitor for a murder she did not commit—and haunted by the ones she did—Wren is a fugitive in both worlds. Hunted by her own people, pursued by the humans, and chased most of all by the man she cannot forget, she is left with nowhere to turn.
Prince Cassiel never wanted the crown, yet with his mother lingering between life and death, the weight of the kingdom rests on his shoulders. To rule, he must set aside grief, bury betrayal, and condemn the girl who lied to him. But every choice tears the realm closer to war—and every thought drifts back to Wren.
When Wren offers him the chance to regain his sight, Cass must decide whether to follow her into enemy lands, or lose everything to the darkness closing in. Old wounds burn, old desires flare, and the fragile hope between them might be the only thing strong enough to defy fate.

But with kingdoms ready to fall and blood demanding vengeance, can a traitor and a prince truly carve out a world where they can be together?
