For this road trip, my wife has elected that we'll be listening to the audiobook of Dungeon Crawler Carl.
This is my first exposure to the franchise, and I am tennatively enjoying it. I am damn suspicious of it though. We have not ventured fully into Ender's Game "sometimes genocide is the only option" territory, but the book is flirting with some dangerous ideas.
@ajroach42 Carl is kinda the anti-Ender. Well, similar body counts.
