That Girl Montana by Marah Ellis Ryan

This is the true story of how John met, bonded with, and eventually rescued a horse named Montana. Montana's declining health had him headed straight for the auction block where he would be sold by the pound, but this horse's loving spirit changed his own fate... Now, freed from the cramped stall in the urban stables where he lived, Montana was brought to a beautiful home in the country where he could live like a horse rather than an amusement park ride. His new home had two young children, Anthony and Charlotte, with whom he became best friends. This is a story of love and a lesson on how positive thoughts, patience, and humility can pave a road to realizing your most amazing dreams.And if you believe in magic, well there's some of that too.
