Flip it! It's 2-books-in-1! Start with a fictional story about a friendly rocket named Phoenix who becomes best friends with Pyxi, a space rover. Vibrant illustrations bring this whimsical board book to life. Then, flip the book over for a nonfiction exploration of real-life rockets! Photographs and infographics illuminate fun rocket facts. The Rocket and Rover characters make special appearances throughout the nonfiction side to tie the two books together.
