A story where the MC has created a self-sustaining highly sheltered farm environment for everything like food, wood, machinery & tools(forge), power, ammunition etc. Can be in a cave or underground bunker or old missile silo. Gathers his family and friends during war or apocalypse.
One of them may be "My Race is Royal" from Scotland-the-Brave.
Also it may be Sanctuary series from JohnyR.
Book 1 you can find here.
Also there is Stultus and his "In a secret Garden" that can be it.
Hey, that's the reason we all are here.
To enjoy what we read.
I caught so many good stories reading this forum, it would be unfair from me not to try to help someone else :)
