Two shows, “The Hills of California” at the Huntington Theatre and “The Ceremony” at the Joan and Edgar Booth Theatre, contend with old familial wounds. From left: Amanda Kristin Nichols, Karen Killeen and Aimee Doherty in the Huntington's "The Hills of California." (Allison Jean White portrays Joan and also doubles beautifully as the sisters’ mom, Veronica.) As they work to mend fences with family members, they’re also trying to create healthy communication patterns. What is clear is the love that these family members have for each other is far more ferocious than any hurt that’s occurred.
