About the product and delivery: No complaints. The font is slightly large and I actually prefer it. About the book: I know it's a children's book, but I decided to give it a go anyway since it deals with space and wormholes. The story is fine and I enjoyed it, but the ending is hackneyed. It didn't make me hate the book, but left me unsatisfied. Overall, I don't regret spending time reading it, but I wouldn't recommend it to fellow adult readers. If you have children the age of protagonist (12-15), it might be a good read for them.
