Wyrd Sisters
This, the 5th Discworld book, is the first where Pratchett really finds the style and tone that he would use for the majority of the rest of the series.
A brilliant parody of Shakespeare, Witch stories and fantasy in general it also happens to be the first book in the Witches sub-series (Granny Weatherwax appears earlier in Equal Rites but that’s more of a standalone DW book).
If you’ve never read it before I very highly recommend it.
It’s a great wee book that I’ve knocked down the score of because there are better Pratchett books out there now and I’m way too familiar with the book now and have rung much of the humour out it – even though I’ve not read it in at least 7 years.
