You should definitely give them a re-read! Maybe it’s because I’m older now, but I’m catching so much stuff this time around that I missed. Also, the humor. The book is subtly funny AF. The foreshadowing is brilliant as well.
About the author though—do you think he’s retired and possibly given up on the series now? As far as I can tell, he hasn’t published anything in a while.
For some reason I thought that was published in 2017. Also, I think it’s a Lit RPG. I’ve never played/read one of those before. I may give it a try too.
