About the Book
Earth and Moonie are solar system siblings who are as close as can be (and not just because of gravity). Together, big sister Earth and little brother Moonie navigate big questions, small frustrations, mysterious Vitamin C, and everyday adventures that feel larger than life. This funny and heartfelt graphic chapter book is perfect for readers ages 6–9, especially fans of Pizza and Taco and Owl Diaries.
