Cursed By the Phantom Prince by Lela Grayce

I was born with a foot in two worlds, but I never imagined I’d hold their fate in my hands.
For six years, I’d struggled to control my wild magic and navigate the treacherous Fae courts. Then came the night I accidentally glimpsed a terrifying truth: a creeping darkness devouring magic, extinguishing life.
They called it the black rot, and it was consuming our realm bit by bit.
Suddenly, the Moon Court – our oldest rivals – proposed an alliance through marriage. They sent Lir, a brooding warrior with eyes full of secrets, to guard me during negotiations. I didn’t trust him, couldn’t trust him. Yet every time our eyes met, every accidental touch, sent electricity coursing through my veins.
As the rot spread, I uncovered a chilling revelation: for reasons unknown, this blight saw me as a threat.
With the fate of two realms in my hands, I’ll have to become the queen I was born to be—or watch as everything I love crumbles to dust.
