When Heather Barlow returns from Africa, the joy she felt during her missionary trip fades. She's still suffering from unresolved grief over the death of her friend Ian, and now that she's back home in the United States, she feels directionless. And while Heather has changed a great deal, her family has not. She is discouraged to see that her sister, Amber, seems no more mature than when Heather left, her parents no less involved with a medical practice that caters to the wealthy.
