DONNCHADH
I only had one mission: steal Princess Celeste from her kingdom and bring her to be married to a warlord. I didn't mean to fall in love. But the more time I spent with her, the more I knew that I'd never be able to leave her in the hands of a cruel man. I couldn't let her go.
My job and family were at stake. My brother left the planet and my sister and I were paying for his mistakes, a huge debt that was nearly impossible to pay.
If I delivered Princess Celeste to the warlord, the slate would be wiped clean.
But I don't think I can, not when my heart says that she's the one for me.
