The Veiled Kingdom

A princess runs from the palace of her father, a cruel king who has taken any chance of a future of her own. On the streets she is hunted from two sides: the tyrant's reign on one, a rebellion against him on the other. The rebels catch her, and none of them knows she is the king's missing daughter.

They give her a choice: join their cause or die by their blades. She joins, and keeps her identity hidden. Dacre, the son of the rebellion's ruthless commander, distrusts her but is drawn to her all the same. He lets no one else lay a hand on her and tries to shield her, yet he also threatens her whenever suspicion wins out.

The longer she stays, the closer she grows to the rebels and to what they are fighting for. Her loyalty to her kingdom starts to pull against her devotion to Dacre, and the secrets she carries reach well beyond the hidden place where the rebels live.

This is a fantasy romance told in the first person, built on enemies to lovers and forbidden desire. It is scorching, so expect a high-heat love story, with constant danger and a heroine split between duty and want. The author also wrote the Stars and Shadows series.
