This was a great book for people like me. I learned about most everything in this book in high school science classes, but that was almost ten years ago now. This book was a great refresher! If you already know a lot about astrophysics I think the information in this book will be too basic to be entertaining. On the other hand I think if you know nothing about the topic you'll either think the descriptions are too vague or be overwhelmed by the facts being thrown at you. So, like I said, I thought this book was great for me, but I definitely wouldn't recommend this to just anyone.
