Engaged to the Enemy

Princess Briannah Snow of Winterland is next in line for the throne, as is Peter Parker of Ironland. The two kingdoms have been at war for many years. King Steve and King Tony used to be good friends before something terrible happened to King Steve's wife and he blamed someone in Tony's kingdom.
For years there has been a horrible war, and many have lost their lives.
Neither of the kings will talk so Queen Pepper and Prince Will, older brother of Briannah who has given his title over over to her, have taken the liberty to arrange for Peter and Bri to be married to end this horrible war and bring the kingdoms back together.
