Cat's Cradle by Kurt Vonnegut
Cat's Cradle is one of Vonnegut's better books. The audiobook also includes a brief interview with the author, though that does not add much to the book.
The story centers around an author who is trying to write a book about the experience of the nuclear bomb. He contacts the children of the scientist behind the bomb and asks what their experience was when the bomb went off. He received responses and got to know the family better. We learn that the scientist was a rather peculiar man. His wife and children also had their strange traits. The scientist had also been asked by the marines to invent something so they would not have to fight in mud. He had actually done it, though he had not widely shared it. This was "ice-9" a substance that is a "seed" that changes the crystallization and melting point of water, and can pretty much caused instantaneous freezing. Each of his children had a small amount. This would lead to the end of the world.
The novel also ventures off to a nation where all religion is banned, especially the "national" religion. This religion is quite quirky and extremely contradictory. The leader of the company is on his death bed and a seemingly random outsider is asked to be leader. Leadership pays well and comes with dictatorial responsibilities, but nobody wants it. However, the old leader dies with ice-9 and most of the world gets iced over. The few survivors can survive by melting off ice.
There is some crazy science here (which is not fully explained) as well as plenty of social commentary, and just plaine zaniness.
