A captured princess. A Demon King. A kingdom on the brink of war.

Princess Hanablessa expected to die at the hands of her enemies.

Instead, she is given a far more dangerous fate: becoming the personal concubine of Razzoth, the feared Demon King whose court is a nest of political intrigue, shifting alliances, and deadly secrets.

To survive, Hanablessa must conceal her true identity while playing the part of a woman who belongs at the king's side. One wrong word, one familiar face, one careless mistake could expose her and turn her capture into an international catastrophe.

But Razzoth is becoming a problem of an entirely different kind.

The Demon King is ruthless, commanding, and dangerously tempting. Behind closed doors, the power between them takes on a heat Hanablessa never expected, built on trust, choice, and a mutual willingness to surrender control. Every stolen moment draws her deeper into a relationship she can never afford to let the court discover.

Because Hanablessa is hiding more than her heart.

As rival kingdoms threaten war and enemies circle closer, Hanablessa and Razzoth must decide whether they can trust one another before the secrets surrounding them become impossible to contain.

She was never supposed to fall for the enemy.

He was never supposed to give her the power to choose.

And if anyone discovers who the Demon King has taken into his bed, they could both lose everything.

Concubine to the Demon King is a fantasy romance filled with forbidden love, enemies-to-lovers tension, secret identities, political intrigue, and consensual power dynamics, where the most dangerous thing in a court built on deception may be falling in love with the enemy.
