This little book was a very pleasant surprise for me. I got it for free on my ipod from feedbooks yesterday evening.
It's a very quick read and has many adult themes in it such as (minor) S/M rituals and male/male romance. The most striking thing for me, was the universe that the author created. A bleak, undefined, post-war future where cloning is accepted( and cheap) and cloned boys are kept as pets/slaves. They are completely dependent on their onwers and not allowed to have any feelings, let alone display sexual interests, since it's forbidden and dangerous to do so. Meigeharen is one of them.
I would personally describe this as a sort of yaoish version of "Bladerunner". Give it a try, you'll definitely find it an interesting read, I sure did :D
