I was poking round Amazon UK last night, looking for Anya Seton's novels in ebook form. Most of them are more expensive than the second-hand paperbacks, but I found this one at a bargain price, £0.99
I'm not sure how long it will be at this price.

I read this when I was about 16 and doing my O levels; it was recommended as a useful book while we were studying Chaucer. I don't remember much of the plot, but if you haven't read it recently, it's worth reading.
