In our seventeenth episode we join everyone's favourite dysfunctional coven - and guest, writer Nadia Bailey - as we return to Lancre for Terry Pratchett’s 1992 Discworld novel, Lords and Ladies!

The Lancre coven have returned from their trip abroad, but despite the impending royal wedding of Magrat and King Verence, all is not well in the Ramtops: it's circle time, when the walls between worlds are thin, and in the witches' absence someone has been toying with powers beyond their understanding. As usual Granny Weatherwax thinks she can sort everything out herself: facing down a young witch wannabe and keeping the Gentry at bay. But Granny is off her game. Is it the arrival of an old flame? Or is her time as a witch of Lancre nearly up? She'll need Nanny and Magrat's help to see off the threat of the Lords and Ladies...

Bringing us back to the witches after only one book away, Lords and Ladies is a particularly Pratchett take on the ancient Celtic stories that inspired modern ideas of fairies and elves. One of the few novels to cross the streams between the witches and wizards, it also gives us more of a glimpse into Esme Weatherwax's past, hints at the future of witchcraft (and royalty) in Lancre, and introduces the infamous "Trousers of Time". Is this your favourite witches novel? What do you think of the parallel universes, other dimensions and alternate timelines it describes? And is this the best take on elves since Tolkien? We'd love to hear from you! Use the hashtag #Pratchat17 on social media to join the conversation.
