This book is about Friendship. You also learn about ranching in that time. It about Luke and Ray and North Flat Ranch. There some Historical in the book. It based on a true story with some fiction in it. I completley story. You learn somewhat what to do when in a thunderstorm. Though most of this book is about cattles and the lives of Luke McKeever and Ray. I really enjoyed this book and I was really would recommend it if you you enjoy Cowboys or Ranching and a bit of History.
