This was the first book I have read by Issui Ogawa, and I got to say that it's a very pleasant surprise. It's clearly soft sci-fi and military/action oriented, but none of that crap "Let's kill them all!" or enemies attacking for no apparent reason whatsoever. It's also one of the few samples of japanese sci-fi fiction, which from my experience so far is quite peculiar.
The story is about a cyborg, named Orville, who has the mission to protect humanity from an enemy composed of self-replicant machines, who resemble mononoke (monsters in japanese mythology). Oeville and others like him, have to protect humans in every places from ET's (Enemies of Terra, not Extraterrestrials) and in every epoch. The novel is also about, to a lesser extense, about Miyo, a shaman queen in ancient Japan. However, she is equally important to the story and to the salvation of humanity.
The rough part of the cyborgs' job is when they have to protect humans everywhen. The cyborgs (with the general name of Messengers) dwell more and more into past, starting in the 2000's, going to the World War II epoch, and the 400's or 200's in Japan, all the way to the dawn of men. Of course, like in every other well-thought fiction, this has consequences, especially to the Messengers. To be honest, Ogawa wrote some pretty cool consequences.
One thing that I found very interesting was the composition of the cyborgs. They have manufactered minds (from what I apprehended) and human enhanced bodies, permiting them a period of discovery of the world around, like the babies but with fully developed bodies and minds. What normally reaches the general public is quite opposite, human brains in robots.
There was something I couldn't take my mind off, which was the enemies. Their way of "reproducing" is something I read and seen a few times before, in books and TV shows, like Stargate (which I hated) and a few animes. Not a overly negative aspect, but kept nagging me all the way.
Very enjoyable and good as a quick read (less than a day is enough) an it's very enjoyable. Can't recommend it more.
Till next time,
