In 1926, ten-year-old Kate, living with her family on a ranch in Alberta, Canada, is convinced that the Quarter horse she receives for her birthday can win the cattle cutting contest at the annual fair and determines to participate even though the contest is open only to boys.

Sheena loves playing with her puppy pals-- chasing water rats and eating croissants at the Main Street Bakery. But now she has to spend her mornings with Amber, a prissy poodle who doesn't seem to know a thing about being a real puppy.

Kate is thrilled when she receives the Quarter Horse she has always wanted for her tenth birthday, and she can't wait to ride him in the cattle cutting contest, but when she learns that no girls are allowed to ride in it, she decides that some rules need to be broken.

Cassie Sinclair and Hillary Craig are in for some rough times when Hillary becomes so jealous of Cassie's new horse that she pulls some dangerous stunts.

Because Sara has a kind face, Wales, a talking donkey who claims he is an enchanted prince, asks her for help in breaking the spell.
