How do Harry and Sir Charles and Amelia reconcile and what is the end result of relations between the Hill folk and the Homelanders?

Harry has another child, this time a female with red hair whom she names Aerin Amelia. When the child is of six months, she, Forloy, Innath, Mathin, Jack, and Corlath all ride to the west to invite Sir Charles and Lady Amelia to the naming ceremony. Within hours, Amelia is hugging Harry, crying, and promising they will happily come to the ceremony. Sir Charles and Corlath's meeting is more tense, but is successful. Relations between the two groups improve as it is discovered that Charles forced Homeland to accept that Jack and his men had not deserted, but had fought a real threat against Home, and they were then listed as honorably missing in action.
