Mission to the Headhunters by Frank & Marie Drown

What does it take to rescue warring jungle tribes from self-destruction? For Frank and Marie Drown, an average American couple, it meant 37 years of living and making the gospel clear to the head-hunting Shuar Indians and their traditional enemies, the Atshuar. Frank's name is inextricably tied to the 1956 story of five missionaries martyred by Waodani Indians in the Amazon jungle, recently portrayed in the movie, End of the Spear. Drown helped lead the search party that recovered the bodies of the slain missionaries.
