Beauty and the Villain by V.F. Mason

Once upon a time I had it all.

I thrived in all the power and luxury this world had to offer.
Until I found out the hideous truth.
When a man I considered a friend betrayed me in the worst possible way.
The scars on my body burned anew every single day as I only craved one thing.
Revenge.
And to execute it I had to strike him where it would hurt the most.
His family.
I patiently waited in the shadows for more than a decade for his beloved daughter to grow up.
Unaware that a villain was ready to steal her far, far away.
I used to be a prince once.
But a certain underworld king destroyed my life.
The price for his betrayal is his daughter: the princess of the dark castle.
