But wait, what is that? Through the telescope, Isadora spots a shooting star that falls to Earth! After courageously finding the place where the star landed, Isadora discovers a new twinkling friend. Her name is Nova, she is a Glow Sprite and she is not supposed to be there. Even worse, Nova's moon kitten Pluto is lost and she needs Isadora's help to find him.

Between magical campfires, space lessons, moon cheese and a glowing sleepover, Isadora will need to use all her wits to help Nova finding Pluto before her new friend has to fly back to the stars.
