Having read the (wonderful! recommended!) Rurouni Kenshin manga, I had to “finish it up” with this book. The story is by the original author, but written in prose style by someone else. The stories are both included in the anime, but are changed a little there. There’s the incident with Sanosuke’s artist friend, as well as the story of the kid with the Jules Verne book Voyage to the Moon World, from which the title of this book is taken.

Personally, I felt that the stories in this book aren’t as strong, nor are the supporting characters as well-developed, as in either the manga or the anime. Then again, there were some historical citations in the back of the book that I personally found useful in finding out more about the actual historical reality behind Rurouni Kenshin. So, it was worth it to me, but to a less historically-inclined person, I’d say stick to the manga, or the anime.
