From the author of Unicorn Princesses, a high-flying chapter book series about a girl who goes on magical adventures with the Pegasus Princesses. When eight-year-old, pegasus-obsessed Clara Griffin is playing in the forest, she's thrilled to discover a magical silver feather and a flying armchair that transport her to the Wing Realm, the land of the pegasus princesses! It's Lucinda's birthday, and Princess Star has planned a spectacular surprise for the pegasus princesses' winged pet cat. Lucinda's cousins, the mooncats, have agreed to host a party in their palace on the Catmoon-the Wing Realm's very own moon. Clara and Star fly in a magic spaceship to meet the moon creatures and prepare for the party. But as soon as they start cleaning and decorating the palace, mooncat mayhem erupts. Will Clara and Star be able to save the party? Featuring black-and-white illustrations throughout and eye-catching, sparkly covers, this series is another must-have for chapter book readers.
