My little boy aged 6 was over the moon to open up his envelope and find a book about Space. We loved opening all the flaps and absorbing all the factual information inside. It is so in depth and beautifully illustrated but done in a fun and engaging way to capture a child's imagination. This has become a firm bedtime read and has led to many other questions. We love the flaps, illustrations and facts used inside this book. * Toppsta reader review *
