Throwing Rocks: Without spoiling the plot, what are some good books that involve the threat of weaponizing a planet’s gravity well against its population?
Please if possible don’t specify whether the event actually happens in the book to keep it a mystery.
Easy one: The Moon Is A Harsh Mistress by Robert A. Heinlein is an early example of this theme.
The Expanse book series also mentions this possibility.
I think I might have to add those to my reading list then 👀
The Expanse series is always a good read.
