 Everybody knows this story. Even people who haven't seen the two big Hollywood treatments of it. Which are both quite good by the way. Alien seed pods fall from space and grow into duplicates of humans which replace those humans while they're sleeping. There had been alien invasion stories before which had emotionless creatures controlling or replacing us. But this was uniquely done and uniquely frightening. I read it for the first time just now and at first I was very pleased with the writing style. It was both charmingly antiquated and could have been written today. There was no time wasted. It got straight to the action. And it was refreshing to see a group of protagonists who were all smart, who all caught on immediately. And who were very proactive about doing what they needed to do. The second half of the book though, it got really talky. Lots of standing around and talking. And then it had a very abrupt and strangely happy ending. Which the aforementioned movies very smartly avoided. You can support 30 Second Sci-Fi and my other projects by becoming a patron. There's a link in the description below.
