WJ American Hero is the final book in the Mountain Family trilogy. This action-packed fictional story begins in 1864 as the family moves to their new homestead in Blue Earth County in southern Minnesota. After the Dakota War of 1862, the largest Indian war in American history, the entire Indian population of Minnesota was forced to leave their lands throughout the state. Once the Indian population was exiled from the state, the federal government auctioned the land to the settlers. The Mountain family placed bids at the auction and purchased several parcels of Winnebago Indian land in southern Minnesota. As the family was attempting to get settled in Blue Earth County, three of its members made the decision to leave the family's homestead and head west to the new frontier of Wyoming. The travelers from Minnesota soon realized that they would be facing an increasing amount of danger every day. They could have never been prepared for what was in store for them in the Wild West.
