The Flawed Princess by Alice Ivinya

Is forgiveness too high a cost to save a kingdom?
Violet is hidden away by her father, a provincial lord, for having a deformed foot. She is tired of being ignored and longs to help her people, who have been abused and suppressed by the court for generations. Their ancient magic is almost forgotten.
When she is caught up in a deadly rebellion, Violet is taken hostage by the king and dragged to the capital. A prisoner deprived of friends and family, she is thrown into a dangerous world of politics and strange magic, where men and beasts are bonded together. Violet realises she must quickly learn the rules of the castle in order to be a voice for her forgotten province.
But the bonds that tie people are fragile, and true evil lurks in the shadows of the castle. As war and assassination threaten to break the kingdom apart, Violet realises that to save it, she must learn to forgive her captor.
And maybe even allow herself to be loved.
