I finished The Shadow of What Was Lost by James Islington and Nation by Pratchett this week.
Shadow was ... fine. Sort of a store-brand Sanderson. Interesting enough setting and magic, but the cast of characters was pretty big and they were all pretty bland. The story itself was actually pretty interesting, but it was a bit of a slog to get through. I may continue with the series if I can grab them on sale, but I'm in no rush to do so.
Nation was a delight. Pratchett said it was the finest book he ever wrote, and while I wouldn't place it at the very top, it's definitely in the conversation for the top 5-10. Most authors couldn't take such an stereotypical setting (shipwrecked white person meets indigenous people on a tropical island) and do it justice, but Pratchett isn't most authors. The more I think about it, the higher I'd place it in that 5-10 range. Read this book, full stop.
