Cover of “The Cat Who Walks Through Walls” by Robert A. Heinlein.

The Cat Who Walks Through Walls by Robert A. Heinlein is the very first and only Heinlein book I’ve ever read. I’ve been told for years what a good writer he is, and that I ought to read his works. So, I picked one at random (well, not entirely by random, as I really like the cover art by Michael Whelan on this one) and read it.

I liked this book until about two-thirds of the way through it. The dialogue was quite entertaining, moving along at a decent clip (it reminded me somewhat of the witty banter and dialog in the Gilmore Girls TV series), and I liked the characters for the most part, at least until I got about 2/3 of the way through the book (everything hinges on this, and I’m not the only one who noticed this).

Heinlein seemed to be preoccupied with sex of all kinds for a lot of the book, and he really cranked it up in the last third of the book. It was as if he reverted to being a teenager driven by raging hormones. This was quite distracting (not in a good way) from the story, and only served to begin ruining for me the entertainment value of the book.

Then there’s the “ending”. It reminded me of the ending to the movie 2001 as it made no sense and seemed to have nothing to do with anything in the rest of the book. It felt like Heinlein was on a deadline, and that he had a strict limit on the number of words he could use, so he simply ended things as quickly as possible. Like a TV series which has been cancelled and has to quickly wrap everything up before the last scheduled episode, it left me unsatisfied and annoyed.

I wanted to like this book, and I did for the first two-thirds, but the last third just made it barely mediocre. If you have nothing else to do (your oven has been cleaned and there are no tile grout lines needing cleaning with an old toothbrush), you might enjoy this book, but even Robert Jordan’s The Eye of the World is better than the ending of this book (and I really don’t like Eye).

If Heinlein’s older books are like the first two-thirds of The Cat Who Walks Through Walls, then I will probably like them. If they are like the last third, I will likely not read any more of them. Ever.
