The Midwich Cuckoos

The story was quite good, but how could it not be? Everyone in a small town collapses into a deep sleep, some kind of invisible force field prevents anyone outside of the town from entering, and then when the force field lifts, every woman in town is pregnant. Yeah, that's gonna be good. And it was made even better by the audiobook, which was actually made for radio. Instead of just a normal narration, there was an actor for every character, there were sound effects, there was music. It was really cool and it definitely made me want to look into more radio productions.
