I will always say read first then listen or watch the show if a book is so fortunate. in this circumstance, I would say it is 100% ok to listen first with this entire series. Jeff Hayes is amazing and covers a massive and vast amount of colorful characters. The editing is solid and of course, it’s Dungeon Crawler Carl so the story is fantastic.
Currently reading Book 7 while I listen to the audio books all the way through. Definitely the best route to go to cure that wait for the next book depression.
