Noah Gates (Unabridged‪)‬

Noah Gates is a family appropriate Western novel. Noah starts out to find the thieves who stole his herd of trade horses, but time and weather wipe out all signs of their movements. With nothing else pressing on his life he wanders to Deadwood for the winter and then to Dakota Territory, with troubles and another theft along the way. Heading towards the Colorado gold fields he agrees to guide Dora across the Montana plains, leaving her in Miles City. After a summer in the high up mountains he decides to find Dora again. Humor and romance ensue. 

Noah Gates, although not a true sequel, has many tie-ins with Hamilton Robb.
