Betrayed by a Deadly Masquerade

Princess and My Husband were childhood sweethearts.
When the Rebels besieged the city, she killed me, using my corpse to take her place, pretending to choose death over surrender.
My body was personally delivered to the Rebels by My Husband, yet he failed to recognize it was me.
After quelling the rebellion, the Princess nestled in his arms: 'Quinn, the King won't stop us from being together anymore.'
I thought they would finally become the lovers they were meant to be.
But then I heard My Husband ask her: 'Who was that woman who died in your place that day?'
