Adventurous original fiction chapter book series inspired by DreamWorks Spirit Riding Free. Spring is the season of change, and things are changing in Miradero - Lucky, Pru and Abigail will soon be heading off to Palomino Bluffs Riding Academy! Before they go, the PALs want to become Frontier Fillies Trail Trainers. But to do that, the girls need to find and train a brand-new horse-something Lucky has never done! It seems as if everything is coming together when the PALs fall in love with a mini horse named Sandy and are given the chance to train her before the Miradero Founders' Day Parade. But training a horse turns out to be more difficult than Lucky could have imagined. Sandy likes kicking, doesn't like being ridden, and refuses to listen to any of the PALs! Join Miradero's favourite PALs as they explore the frontier and beyond!
