The City of Ember
This is a quirky YA science fiction novel that was turned into a film a few years back.
While I quite liked the film general opinion online was that the book was much better.
To be honest, while different in ways, the book is pretty much the same thing.
The thing I liked most about the book was the world building. The general air of everyone muddling along and not really knowing how anything works in a city that’s falling apart and running out of resources really worked.
It’s worth reading I just didn’t feel it was at all exceptional.
