I am re-reading a great book that has been out of circulation for some time. The book is called Hiero's Journey by Sterling Lanier. This was one of my Dad's favorites, so I read it as a boy, again in my early 20's and now again in my late 30's. I have enjoyed it immensely each time. It was released in 1973. It takes place on a post-apocolyptic earth. Per Hiero Desteen is a warrior-priest in the old Canada. It is 5000 years after a massive nuke war and there are all sorts of Leemutes (lethal mutants) in the world. Hiero has to go on a quest to find some ancient technology to save the Abbey (forces of good) versus the Unclean servants of evil. I am sure that this book had some impact on the development of Gamma World and probably some influence on psionics in D&D- although my Dad was against putting psionics in AD&D. Have any of you read Hiero's Journey? What other books have you read that gave you great game ideas or are just a great read?
