Flying U’s Last Stand [EPUB ebook] 

This book takes you back to Montana’s Flying U Ranch with its wonderful group of cowboys. Andy Green, Pink, the Native Son, Irish, Weary, and Happy Jack were all here, along with Chip and his wife the Little Doctor and their son The Kid (real name Claude, and he is six years old and big for his age). The gang has to deal with changing times, progress, and civilization, all of which threaten the very existence of the Flying U. Homesteaders! Farmers! What can be done to protect the home country from these people who have no idea that the land claims they are wanting to prove up on are not meant for farming? (Goodreads)
