Don Richardson is one of the most read authors on Christian missions alive today. Peace Child, a book about his missions work with the Sawi people in Irian Jaya, sold about half a million copies in 27 languages, was a Reader's Digest book of the month selection, and became a film that's available in 26 different languages. He is also the author of Eternity in Their Hearts.
