This book quickly became a bedtime favorite, especially with my oldest (5). He loves the rhymes and tracing the constellations. We read this story before bed and he always talks about riding the train to Constellation Station and finding new stars and planets that no one has ever seen. This book is educational, teaching about some of our favorite constellations, but it also encourages so much imagination and imaginative play. We love and HIGHLY recommend this book. Especially if your kid(s) have even a remote interest in outer space.
