Princess Evie and her pony go on a magical adventure in this third book in an enchanting chapter book series about a princess, her stable full of ponies, and the amazing adventures they share. Evie and her Haflinger Pony Indigo take a magical journey through the tunnel of trees and arrive in the Rainbow Garden just in time for the annual Rainbow Blossom Festival. But as Evie and her kitten Sparkles lend a hand getting everything ready for the celebration, the Rainbow Girls’ winged pony Corolla–who is supposed to pull the chariot in the parade–goes missing. Evie and Indigo join the hunt, and when Corolla is finally found, all the girls are in for a wonderful surprise!
