Just as Arthur Dent's sense of reality is in its dickiest state he suddenly finds the girl of his dreams. He fids her in the last place in which he would expect to find anything at all, but when 3,976,000000 people will find oddly familiar. They go in search of God's Final Message to His Creation and, in a dramatic break with tradition, actually find it.

 
Nope, you guessed it, I've not read this either. And not because I didn't want to, but because I never plucked up the courage to ask Sarah (who is infinitely more picky about the condition of her books than I am, against all probability) if I could borrow her copies. That I and I didn't buy them sooner. Anyway, now I have my own copy and I fully intend to start reading it soon.
