The Shepherd’s Crown is the fourth installment in the Tiffany Aching subseries set on Discworld, written by Terry Pratchett. Pratchett passed away earlier this year and this is his final published work. On a personal note, it is a somber thought to think that I have read every Discworld story there ever will be.
Tiffany Aching is a full witch these days, the only witch of her homeland known as the Chalk, a land of sheep and plains, though she has a strong bond with the witches of Lancre who trained her in witchery. She spends her days taking care of the business of witching, which is mostly a matter of taking care of practical everyday things–bringing food to the homebound elderly, helping people with their ailments, being a sort of broom-flying country doctor.
