Endless Horizons covers 100 years of the Prettejohn family in Kenya. This book starts in 1904 when Jock ‘Black’ Harries came to Uganda with the King’s Africa Rifles, moves on to Jock’s pioneering cattle ranching near Njoro, to World War I, to Mike’s grandmother coming to marry Jock, to Mike’s father managing Jock Harries’ stock operation, to Naro Moru where Mike’s father bought his own farm, to Mike’s schoolboy adventures, a trans-Sahara expedition, the Emergency, and then on to Mike buying his own ranch in Mweiga and becoming a professional hunter and managing massive cattle/game ranches in Galana and Taita before ending his career in conservation. The last chapter tells of Mike’s efforts to save the critically endangered bongo. The book is epic in proportion, yet takes time to focus on the small details of life that make it authentic and personal. The book includes over 80 photographs, many published for the first time.
