This is a real page-turner, the most interesting novel I’ve read in a while. Very good worldbuilding, and a nice “narration twist” as I’ll call it. This book really just sets up the story for (I guess) the following two books; the majority of it is flashbacks of the main character’s life as an Imperial Fulcrum orogene.
The orogenes, or roggas, are individuals with an inherited trait of being able to control earthquakes and the like. For the most part, they are shunned by society, since they are seen as destroyers of civilization and all that’s good — at times past, certain orogenes have either intentionally or accidentally in a fit of passion raised a volcano on their city or something similar. The Fulcrum, a school and governing body of orogenes, is the only authorized user of their powers. It is watched over carefully by the Guardians, superficially polite but under the surface almost cruelly inhumane towards the roggas.
The “Fifth Season” per the title is Death. In this world, catastrophic seismic events which more or less end civilization occur every few hundred years on average. Besides the event itself, the real killer is the years of nuclear winter which usually follow. The different communities, or “comms” are built around vigilance and eternal preparation for surviving the next inevitable apocalypse.
The main event here is an engineered apocalyptic shake, which seems to have the potential for a Fifth Season much longer than ever before. And the instigator is actually one of the “good guys.” I won’t spoil the story any further; just will say that there’s lots of mysteries in the world-building vein which get revealed as the book goes on, only to reveal new mysteries later. I guess that’s the definition of good pacing?? And the narration twist is pretty good.
