Hope you do give Terry Pratchett a try, Jo. I find his books a real boost when I have loads of free time, or I need to rest up.
I love the characters he creates, the keen observations he makes, his sense of humour, and the way that the books are so easy to re-read. His female characters are so strong and well-rounded, which is brilliant.
Most of the time, I can only re-read a book perhaps twice, but his I can read over and over. With the first few books, I found that I had missed several jokes at the first reading 'cos I was too busy laughing at the one that had come before.

Some should never be read on a train (or anywhere in public) because random sniggering or outright guffaws get you funny looks!
If you get hooked on it too, there are two key places for further fuel, such as the alt.fan.pratchett group on Google Groups and L-Space. The annotations for the books help you get jokes that might have passed you by, or pique your interest into reading other things.
He has had to slow down a little since he developed his Alzheimer's problems (or rather, since they really made themselves an "embuggerance" - his own new word!).
The Ankh-Morpork Knitters regularly have themed knitting projects.I keep seeing the swaps on the group in Ravelry, but I have never joined one because I'm not entirely sure how it works. Perhaps one day!
