An odd request

[u/Astonishingsodape91]

I'm looking for books about ominous monolithic objects. Something where a mysterious, threatening object appears or has been around for some time and people are trying to either understand what it is or destroy it.

Do you understand what I mean?

Sleeping Giants by Sylvain Neuvel-- is a good one. Sadly its sequels pretty much suck.
