It's pretty good. It introduces the reader to the story of Isis and Osiris, two Gods in the Ancient Egyptian Myth, but it doesn't tell their whole story, just part of it. I would have liked it more if it revealed the whole story, but for being the part it is, the writer and artists did great jobs.
It's a perfect intro for those just getting into Ancient Egyptian Mythology, and the only fault I can really pin on it is the Map at the beginning of the book. It's a MODERN map, while in the times the story was set, Egypt was a MUCH larger place.
