時間封鎖〈上〉〈下〉

時間封鎖〈上〉〈下〉 (創元SF文庫)。Though I am not maniac on scientific fiction, I read sometimes this kind of books as well as fantasy genre.  It is just because I would like to explore the possibilities of human behaviors given the fundamental change in our environment and/or technological advance.  From this point of view, I like this book very much.
