The first book in an inspiring new series that engages the imagination and shows how we can all make a difference. It’s the start of a new term and Katy can’t wait to have her two best friends over for a playdate. She’s been planning their next adventure all summer, but little does she know it’s going to be out of this world! Katy, Cassie and Zia find themselves transported into outer space when their rocket made out of recycled waste magically becomes life-sized. With the help of Katy’s cat Thunder, the girls navigate their way to the wishing star. But as they prepare to make their own wishes, the girls realise they have a greater mission: to save planet Earth.
