A Western Classic (From the Renowned Author of The Coral Island, The Pirate City, The Dog Crusoe and His Master & Under the Waves)

Living in the Wild West wasn’t always a dream job. There were often skirmishes with the rival groups and an on-going tussle with the Native Americans, who wanted to preserve their own space. But can a group of ‘mountain men’ survive in these environments or will they succumb to the pressure?
