Reign of Betrayal by Amber Bowe

In a kingdom under a malevolent curse, the rulers turn to the Hollows—an underground prison for dangerous criminals. In a cruel plan to save their land, they host a series of deadly trials for the prisoners. Whoever survives will become their champion, the one to end the curse or die trying.

Reign, a fierce and resilient inmate, seizes this opportunity as her only way out and a chance to seek vengeance on those who wronged her.
Lukene, the dark prince, is known for his ruthlessness and a heart as cold as the prison walls themselves. His only concern has always been his duty to the kingdom.
As the trials unfold, Reign and Lukene find their fates intertwined. Amidst the deadly schemes at court, their mutual hatred transforms into something neither of them wanted nor expected.

Betrayals, heartbreak, and dark secrets test their relationship as they navigate the treacherous path ahead. Can their own ambitions survive the perils that a wait, or will the kingdom’s curse or their dark pasts consume them both?
