He Who Fights with Monsters. (LitRpg) Anyone else read/listened to this?

I've been on this LitRPG kick lately. I've listened to dungeon crawler carl, and now I'm on "He Who fights with Monsters" book 4. Where Jason, has been transported back to his original world earth.

Am I the only one who didn't really see that coming?! at the end of the third book, i realized that something would happen. Coming back to earth actually surprised me.

Also does or did, anyone feel like it shifted the tone or pace of the book?
