Hell Divers
I think this works better as a conceptual story than an actual fully written out novel for me. There’s at least another 9 books in this series, so I’m definitely going to be skipping those. This isn’t a bad story at all, there’s a meaty plot that moves along quickly, but there’s not enough world building for my post-apocalyptic tastes, and I couldn’t get over the baseline concept of a floating war machine that’s survived in the sky for over 200 years with only a team of “Hell Divers” going to the surface to pick up supplies from a war torn hellscape infested with unfriendly creatures that might could be the radiological descendants of humanity. The method of getting supplies back up to the sky ships is also pretty dubious, just strapping a balloon to it and letting it drift back up to humanity. If you can get past my personal hangups, then this series might be up your alley!
