NO MAJOR SPOILERS
I love the Discworld series. Every last one of them can sit comfortably in any collection of great Fantasy fiction. Pratchett set the bar so very high that picking a favourite will always cause a lively discussion amongst fans, but this is mine.
For my money, this is where Pratchett really found the style that became such a hallmark of the series. I love his observations about what passes for logic amongst siblings, about sex inequality and about standing up for yourself.
