Book details for My Friend Flicka
The classic story of an aimless teenager, a demanding father,
and aspirited horse -- now a major motion picture from Twentieth Century Fox
A daydreamer and a time waster, young Ken McLaughlin spends his days on his family's Wyoming ranch with his head in the clouds, surrounded by endless blue skies, wide-open spaces, and beautiful horses. To his brusque, practical father, the boy is an enigma and a disappointment. Then one day, Ken's life is filled with new purpose when he finds Flicka, a magnificent filly as wild as she is fast. Though the strong bond between boy and horse only fuels his father's disdain, Ken's growing love for his friend Flicka is changing him -- leading a once-aimless young man down the path to responsible adulthood, forging a new respect and understanding between father and son, and inspiring a fierce loyalty that nearly costs Ken his life.
