The book was pretty good...some things were dated but for a book from 1951 he got alot of things right but some very wrong. I liked he language as it very 1950ish which gave a glimps into how different people spoke what is now long ago (60 years).

I have often found that Heinlein's adult fiction is a little to strange for me, but this was an excellent Heinlein. You cannot consider your Heinlein library completed without this excellent book.

How can you say no to Heinlein? He is a Scifi great, unfortunately not my favourite. Tom Weiner does a very nice job with a very dated story.

Actually one of my favorite early Scifi tales is Heinleins "Have Space Suit will travel". Yes it's dated as well and a such is also a mirror into to times but I found it more enjoyable. While ( Have Space Suit) reflected a more normal slice of time ( Puppet Masters) reflected a time when there was comcern, if not a little fear of alien or something out there. Not having experienced that reference it just doesn't quite feel right to me.

He was very consistent through out the tale and characters.

With few exceptions any story is worth listening to. This one was it simply isn't among my favorites.

It's always worth while reading the of any genre. Heinlein is definitely one of the greats along with Farmer, Cambell, Foster, Leimster and Card it would be better to start with a tale hat draws you in on a more realistic level.

I would recommend reading this book - but definitely not listening to it. The narrator takes all excitement out of the novel. Will not listen to another "Tom Weiner" read book again...

Any of the many narrator's I have listened to recently would do a better job of acting out this novel.

Very good (although aged) science fiction novel. Just not worth the 'listen'. Pick up a hard-copy!

This was easy to read. It adapted fairly well to modern times for as old as it is. One thing that makes it obviously not of modern thought is the ease of which the alien slugs can be overcame on an individual basis. Most alien creatures today are nearly impossible to defeat, yet these slugs can't take a knock on the noggin before they release the host. However, with the limited resources of alien information in 1950-51 it is a good read and for the times it is thought through okay. I would not use a credit on this unless you like out of date alien invasions. The narration was not bad and I listened comfortably on 2X speed. Hope this helps someone. Later

Truly timeless book. Some of the dates that were discussed show that we haven't advanced anywhere as fast as Heinlein had proposed. Still, the book was excellent and a year from now, I will listen to it again.I would guess that this book is where Invasion of the body snatchers was derived or at least it influenced that book.

The story is a bit dated and the reader can pick up on how much time has past since it was written. Having said that it's still vintage Heinlein. Still worth a listen.

Although his crystal ball was off (and who can blame him) RAH is a master at world building, and injecting themes into his work. I enjoy the way he guides the reader along.

I discovered Science Fiction as an elementary student in 1950's. As I recall the first SF book I read was written by Robert Heinlein. I don't remember the title, but I don't believe it was this book.

This book was great fun to read. Heinlein had a view point that comes through clearly, but the book didn't seem "preachy" to me. It's an action packed, fast paced story. Once I got started with it, I found it difficult to stop listening. The book was written in 1951. Some aspects of the book are dated - I expected that. However I didn't find the book as "dated" as I expected it to be.

The only thing that I didn't like was the narrator's "voice" for the female character Mary. The character is a strong, capable woman. The rest of the narration by Tom Weiner is excellent.

There are claims that it's an allegory. No - it's simply awful. Really - it is poor. The only reason I haven't returned this one is I wanted people to read my review and save their credit. I got it on one of the daily promotions.

If you really want a glimpse into gender issues in 1951 America, here's an example...
Spoke by the hero... "She was a better gentleman than I was."

I suppose some will argue that the performer was trying to capture the 1950's. It just does not work.

It took me a little while to get into this book, but by the end I was glad I read it and had some appreciation for it. Not bad for 1951, and the knowing the culture and world events at that time make the book very appropriate for the age.

It took me a while to get used to Weiner's gruff voice. He does an OK job differentiating characters, but his female voices make the women sound big and harry, like they've been taking steroid injections.
