A beautifully crafted world built on the uncertainty of world-ending earthquakes and those with the power to move the earth themselves; a group both used by the now-ended civilisation and abused and ostracised by it for their powers.

I find it a great example of world-building where, instead of starting with “wouldn’t it be cool if people were green” it takes a structural change to the world and expands upon how this influences human society and evolution in a methodical, connected way.  The parallel stories well serve the slow exploration of the world and the #queer poly rep is beautiful.
