Alas, Babylon was good...but not as good as Lucifers Hammer.
spin180...The Rift, while a decent read, is not in the same class as Lucifers Hammer. What it is good for is seeing how fast things can break down locally, and the kind of filth that will move in to the vacuum left by a lack of authority.
On the topic of books, DO NOT read 'On the Beach' by Nevil Shute if you are feeling the least bit depressed. Good story, but the last couple of chapters, I could hardly read through the tears in my eyes. My wife took it away and won't give it back to me.
