Two girls who aren't related now consider themselves "liver sisters." 17-year-old Kendall and 11-month-old Ava were both in need of liver transplants.

After a combined 12 hours of surgery both girls are doing much better. InsideEdition.com's Mara Montalbano (https://twitter.com/MaraMontalbano) has more.
