Aristana was once first in line to inherit the throne of Yiogrante. But after being charged with killing her own brother, her siblings vie for the throne that was almost hers. With her hopes of becoming empress shattered, Aristana lives every day as the imperial disgrace until she meets Marquess Patelo, an admirer who has come from the future. He knows she will rule the empire one day, but she no longer wants the throne. She'd rather ruin everything and everyone who has ever caused her pain!
