In future America, the states are divided into six areas, called Delegations. Each Delegation is different. Our story takes point of view of Malthace, she lives in Delegation Six. Her Delegation is very free, but brave and bold.
Even though there are six delegations, they are ruled by The Domain, the seventh Delegation. Each year, boys 15-22 from The Domain send letters to the Delegations to get engaged to any girl their age. Once a girl has been engaged they have to live in The Domain with there husbands forever, unless you escape. If you escape, you will not be free of your engagement, unless you make it to twenty-two with out getting married, or someone else claims you as there fiance.
Disclaimer: There will be a lot of mistakes made and it's not completely medieval as this is fiction and also twelve centuries into the future. This also no a copy of the Selection book series as I just stumbled upon those books a month ago.
