The Cat Who Walks Through Walls by Robert Heinlein

I expected this book to be much worse than it actually is. I've never heard many great things about the 80's Heinlein books and as a high schooler I remember being impressed by a few of his 50's and 60's books. I had read Puppet Masters, The Door Into Summer, Farnham's Freehold and Citizen of the Galaxy. I remember being impressed by them but I reread A Door into Summer recently and found it almost unreadable. The dialogue is terrible and the "science" is hopelessly outdated. Also the relationship between the twelve year old and the main protagonist is very odd and creepy. The main character freezes himself to speed up the time when he and the twelve year old can get married (I think he waits until she is twenty-one).
Henry James wrote a book in the 1800's (I've never read it but I've heard the plot described) Roderick Hudson. Hudson takes in an orphan and raises her and marries her when she turns 18 (the old Woody Allen routine).
The Cat Who Walks Through Walls moves at a fairly brisk pace but some of the dialogue between "The Col." and his centuries old (but good looking) wife is sometimes excruciating, especially when it's sexual. And there's a twelve year old girl involved that the Col. is tempted to sleep with (who is his wife's granddaughter). Again very odd and very, very creepy. I'm only 2/3's the way through and I've read many reviews where people say it slows down considerably half way through. I haven't noticed any considerable slow down yet but the plot is getting convoluted.
So far this book is about what I expected but a little better than I thought it would be. Heinlein's grasp of what the Internet can do in 1985 is pretty spectacular. The "terminal" that's in every home handles all news, shopping and personal correspondence and the fact that he is projecting 150 years into the future but we have this technology 25 years after he wrote this shows just how fast we are moving technology wise.
