I know why my Honey likes books by Hugh Howey.
A cozy experience of well-contained, chamber setting. One that can be made believable through attention to small details. And one that is very similar to a Generation Ship environment. Only you know, a Generation Silo.
The TV-series is in ongoing release while I'm writing this. But I promised her we'll watch the rest of the episodes together. And in the meanwhile I can listen to all the stories as they were written.
(Yes, fiction these days is consumed in an audiobook format mostly. The amount of text to process daily is enormous; besides, I've already built up a habit.)
