Would you recommend people the Shepard's crown on account of it being Pratchett's last work?
Not to start with, no. In fact I firmly recommend reading it last if you intend to read the whole series. There are things about it that mean something different after reading everything else; it would be tough to start with for a new reader who wouldn’t have all that context.
That said, I do recommend reading it at all. I know some people have put their copies aside because they aren’t ready yet. I held onto mine for a year. I get it. Sometimes it takes time. But go easy on a resolution to never read it so it will never be over. It was written to be read. It has some important things in it. And after you read it, well, no, there won’t be any more. That was the last one.
But it isn’t over, not over over, the way things are when they’re dead. The Disc is too big for that; we know it because we’ve been there so many times and every time we go back it’s been moving even while we were away. I’ve been reading and re-reading these books for over half my life and I still find things I’ve never noticed in them before, little bits and pieces of the Disc that I’ve never ever seen. And sometimes things I’ve seen a hundred times look totally different through eyes just a few years older. And sometimes it’s places I’ve been and things I’ve seen before, all familiar, all recognizable, and that’s good too. It doesn’t have to be new. The familiar places just start to feel like home.
If you decide never to read it, I understand. Sometimes it’s just nice to know that it’s there, that there’s still an adventure that you can have for the first time. And, hell, reading it isn’t easy. It’s probably the hardest time I’ve ever had reading a book, if only physically because it’s hard to read while lying on the floor in the fetal position.
For me it was worth it. And I do recommend it. But ultimately it’s got to be up to you.
