Question

Does anyone know of a kids book about a witch who has a spaceship, and some kids who follow her in another spaceship on her voyage to the moon?

It's about some kids who follow a witch in her spaceship to the moon.. The book is purple, and I believe most of the illustrations are as well.

I'm not sure if this is what you're looking for, but there's a book called "Space Witch" by Don Freeman that has a mostly purple cover. The link below shows a picture of the cover:
