A New Song (Mitford Years #5) by Jan Karon

In A New Song, Mitford's longtime Episcopal priest, Father Tim, retires. However, new challenges and adventures await when he agrees to serve as interim minister of a small church on Whitecap Island. He and his wife, Cynthia, soon find that Whitecap has its own unforgettable characters: a church organist with a mysterious past, a lovelorn bachelor placing personal ads, a mother battling paralyzing depression. They also find that Mitford is never far away when circumstances "back home" keep their phone ringing off the hook. In this fifth novel of the beloved series, fans old and new will discover that a trip to Mitford and Whitecap is twice as good for the soul.
