Knight Theo Grenville will do whatever it takes to discover who's plotting against his king. So befriending--and even romancing--his target's middle daughter, Medea, is merely part of his sworn duty. But what isn't? Falling under the spell of a woman who's anything but plain in his eyes! Yet every day they become closer, the more torn he is between his allegiance to his king and his heart...
