The stand in princess

"My king, I am willing to marry that tyrant in place of the princess." I said, trying to get my voice to stop shaking.
I stood in fear as the king acknowledged my presence for the first time since I had entered the room. His Highness eyed me up and down as if appraising a new piece of livestock. Taking a small step towards me, I could hear him muttering to himself about how it may just work. I couldn't comprehend what was going on. How could he even entertain the idea of me replacing a Princess to marry a foreign king?
To protect her mother, Cora marries Tarak Bahl instead of the princess. He’s a brutish former slave from a ruined kingdom, now a king. Can she pull off deceiving such a ruthless man or will she end up as one of his countless victims?
