Jan Karon's Mitford series is a phenomenon in just two years, her books have sold over 2.5 million copies, there's a Mitford newsletter, and this summer Hallmark will introduce Mitford greeting cards. In the audio versions of her books (also super-sellers), Ms. Karon reads. That's an added attraction; her sweet Southern voice is the very sound of Mitford and its marvelously warm-hearted characters. What's new in a A New Song (4.5 hrs) is a new setting and a new set of memorable neighbors. Retired Episcopal rector Father Tim Kavanaugh has agreed to leave the tree-lined streets of his beloved Mitford and become interim minister of a small church on Whitecap Island. Not surprisingly, Tim and his wife Cynthia find both joy and sorrow on Whitecap and find that the members of this new congregation are as challenging and rewarding as any they've known before. Don't worry about old friends; the Mitford folk are never too far away from the Kavanaughs' everyday life and thoughts. Sukey Howard reports on spoken word audio each month.
