I read that when I was about 18 or 19, and enjoyed it very much. i think it's a great time for a re-read.. from my older person's perspective!
What a surprise! I,too, first read it at 18-19 and 20 years on I still find it enjoyable! As a matter of fact I get more things now, than I did back then. I started reading it again (this time in English) because my brother gave me the 5th book in the series, called "Mostly Harmless" which I haven't read (it wasn't published when I read the first four, and still not published in Greek) in order to be able to follow the plot. And not so long ago I also found the 6th installment called "And another thing" Part six of three, written by Eoin Colfer.
One other book I enjoyed very much, some summers, not long ago, was The edible woman by Margaret Atwood.
Do you have any suggestions? I have at least one hour worth of reading time,each day, on the bus to and from work.
