Question: I purchased this book for my 9 year old son as a companion book to several astronomy and constellation guides he requested for his birthday. He completely devoured it in three days - the illustrations are bold and the stories are dramatic/gruesome enough to capture his interest (without being too horrible or nightmare-inducing). We are finding that knowing a bit about the legends behind the constellations makes stargazing that much more enjoyable. I would recommend this book for boys and girls 8-10 years old, although I admit I enjoyed reading it, too!

Answer:
Positive
