This was pretty great. Took me a while to get around to it because while I still love the Discworld books I've been reading them for 20+ years so I like to take a break from Pratchett now and then, otherwise everything starts to seem too much the same and a little expected. Nation reminded me of how much fun reading can be -- so quick, go pass it on to a reluctant reader. Part of me couldn't help thinking of Pratchett's own health while reading it: this is a book about loss and rediscovery of memory, about missed opportunities, about (as they all are) death. And, as ever, with Pratchett, there's a huge swath of his main preoccupation through it: duty. (And there's a touch of Blue Lagoon about it, too, but that's me showing my age.) But all the preoccupations are buried beneath a great story which made me wish Pratchett would write more non-Discworld novels yet also left me refreshed and ready to read more of those, too.
