Bound to the Fae King

Exiled princess turned assassin. I have trained in the arts of magic my whole life and now I have my most important task yet. Kill the King. I must assassinate the fae king to take back my rightful crown. However, not everything goes as planned. My plans are foiled when the fae king weaves a powerful spell binding us together. I pray that hatred for the devastatingly treacherous king serves me well against his charms and looks.
The two of us are forced into a tentative truce when people start turning up dead and the kingdom is threatened by a growing army of nefarious foes that thirst for power and blood.
