Book excerpt: "Set in the 1930s, and spanning the globe, The Good Echo is the story of a marriage between controversial nutritionist and dentist Clifford Bell, and his quietly courageous wife Frances. After their young son dies from surgery Clifford performs, the two seek to escape their grief through unconventional means, traveling from Ohio to Sudan, to substantiate a theory of which Clifford's colleagues are skeptical. Narrated in turn by Frances and Clifford, and by the ghost of their son Benjamin, The Good Echo is composed of postcards and bedtime stories, folktales and family legends, travel and research notes."--Provided by publisher.
