I recently re-read "Stonehenge" by Bernard Cornwell. It's one of my favourite books. It tells Bernard Cornwell's version of how Stonehenge may have come to be built. I've now read it several times, and always enjoy joining Saban as he spends his life attempting to build the temple his brother, Camaban, insists the Gods want built.
I also recently re-read a few of the books from Terry Pratchett's "Discworld" series. I'm reading them in a very random order at the moment, because my cassette copies broke (listened to too many times I guess) so I'm replacing them as and when I can on CD, ending up grabbing them in random orders. Mind you, I wasn't totally up to date anyway, I had most of the first 29 books, but I had nothing after that, bearing in mind there are now 39 of them. Anyway, I recently re-read books 6, 23 and 29; "Wyrd Sisters,"Carpe Jugulum," and "Night Watch." I've said it before, and I'll say it again: I love the Discworld books, and encourage anyone who hasn't done so to read them; especially if you're a fan of fantasy novels!
