Great for space loving kids
Format: Hardcover
My son is super into space and planets and loved this book. It's funny and informative. My son was asking me what stuff was and why it was being eaten up.
What makes it better is with a blue light in the dark you can read the book backwards as a whole new glow in the dark story!
