I can't be coherent about this. I just can't. I cried so hard between pages 37 and 41 that I had to put the book down and go do something else. 
 It's not perfect, and if you read the afterword you'll understand why: it's not been drafted and redrafted to the extent most Pratchett books have, and in places it shows. I do like the way Pratchett, as he always has, acknowledges that most people perceive gender essentialism as normal and natural while absolutely celebrating those of us who don't. Pratchett has always been political with a small p and this book is no exception, but some of the ideas are not as elegantly expressed as we are used to. 
 All that said: this is better than Raising Steam was - which made me incredibly sad because it was so bad and I thought the disease had taken it's full hold and... yeah. This also feels emotionally right as a last ever Discworld book. It's just... I've been reading Pratchett for over 25 years and I haven't - can't - come close to accepting that he's gone yet.
