Frank Lloyd Wright expert, Donald Hoffman, writes a 96-page guide to Kentuck Knob and its history, with more than 50 photographs, drawings, and diagrams. This hardcover book is a must-have for any Frank Lloyd Wright lover, with an introduction written by Lord Peter Palumbo. 

"This is the first thorough guide to the design and history of "Kentuck," a splendid mountain in southwestern Pennsylvania designed in 1953-1954 by Frank Lloyd Wright. Inspired by Fallingwater, the famous Wright house only seven miles away above the waterfalls of Bear Run, local businessman. I.N. Hagan and his wife, Bernardine, commissioned the 86-year-old Wright to design this home. 

Frank Lloyd Wright's House on Kentuck Knob brings to life an unusual work of residental architecture. It is the perfect introduction to Kentuck, and for those who have visited there, a lovely reminder of this luminous but modest house." - David Lewis Carnegie Mellon University
