On my Mastodon account I asked for recomendations for Post Apocalyptic fiction I might be interested in. The thread became very active and the community really stepped up, with not only great suggestions, but also fun and interesting discussions.
I kept a list for my own needs, but the I thought others could be interested too, so here it is.
Huge thanks to everyone!
