Every first Sunday in June, members of the Moses clan gather for an annual reunion at a sprawling hundred-acre farm in Arkansas. And every year, Samuel Lake, a vibrant and committed young preacher, brings his beloved wife, Willadee Moses, and their three children back for the festivities. In the midst of it all, Samuel and Willadee’s outspoken eleven-year-old daughter, Swan, is a bright light. Her high spirits and fearlessness have alternately seduced and bedeviled three generations of the family. But just as the reunion is getting under way, tragedy strikes, jolting the family to their core and setting the stage for a summer of crisis and profound change.
