Robert A. Heinlein
The Amazon.com product description:
Engineered from the finest genes, and trained to be a secret courier in a future world, Friday operates over a near-future Earth, where chaos reigns. Working at Boss's whimsical behest she travels from far north to deep south, finding quick, expeditious solutions as one calamity after another threatens to explode in her face....One of the books I bought last week, I'm sure I've read this one before, but I sure didn't remember much of the story when I read it this time.
Friday is definitely a Robert Heinlein novel along the lines of Time Enough For Love and some of his other books. Not suited for all ages, but for adults, it might be a good read.
The main character, Friday, was an interesting one, as was the world she lives in. Both extremely high tech and at the same time, very low tech. I'd love to know what had set it on the path it was on, which was never even hinted at. At the same time, it was quite realistic with the character attitudes and prejudices that were encountered. A bit free towards sex however, but that's generally a hallmark of some of Heinlein's novels as I've already noted.
To be honest however, I have to admit that this wasn't my favorite of his books. I still don't have a clue what was going on in some ways and the book seemed to wind up too fast. Which again is something I've found true of some of his books. IIRC, it was The Cat Who Walks Through Walls that I found that about before. I think that predates this blog though.
Still, if you like Heinlein's books, it's worth checking out.
