Accomplishments of the Duke's Daughter (Light Novel) Vol. 4

Having rescued her people in the eastern territories and thwarted another plot to undermine Armelia, Iris throws herself back into the work of governing her duchy. After all, it's only through work that she can make herself forget her growing feelings for Dean. But she can't put off all thought of marriage. A foreign prince has come to the duchy seeking an alliance--and Iris's hand to cement the deal. If Iris gives herself to the prince, she secures Armelia's future...and gives up her heart forever.
