OK, can anyone place this one? This was a book that I read years ago, and I want to reread it. This was something of a dystopic future, the government was keeping an eye on everyone. A totalitarian regime. The main character was a young man who somehow got the job of going to this wealthy person's home while they were away and keeping an eye on things. I remember there being carpet rolled up in the house. Kind of a mansion. So he meets a woman and for some reason he is not supposed to have anything to do with her, at least on a more personal level, if you know what I mean. So he takes her to the house he is watching and they start a relationship, and they then get caught somehow and he is accused of miscegenation. I remember that word in the story, so that should be pretty specific. It was a long story as I recall and there was time travel and everlasting life in it. But I could be mixing that up. Does that ring a bell?
