I read books 1-7 on my kindle and had recently started book 8. I hadn’t got too far before I felt like I was missing stuff I should understand about all the outside the dungeon stuff. I decided to start back over before finishing 8 and I’ve been doing the audiobooks this time. I am loving it. Except the AI’s “I’m touching myself voice”. It’s just so creepy I can’t take it – which is a testament to Jeff Hays’ talent!
