Say to These Mountains tells the true story of Wallace Turnbull, one of Haiti's pioneers in development and missions. Over the course of 70 years, his work changed countless lives and influenced national policy in both Haiti and the United States. As told by Wallace's granddaughter, this eloquent biography takes the reader on a journey through the life of a complex man and his adopted country, painting a picture of grace and mercy vastly different from the often-grim stories shared about the island nation and her people.
