It's about a young woman nicknamed "Rosa", after the flower that seemingly grows in her right eye socket.

She lives in a world where, until very recently, people like her -- the Younger Nations -- lived near, though with very few contacts, people of unimaginable powers. They were titans, and the rumors of their power were magnificent. Their magic was far beyond what the Younger Nations could imagine, and the glimpses of it struck awe into the witness.

Then... the titans fought among each other, and in the end, only few remnants of their living remained.

The Younger Nations were not foolish, and went to seize whatever power remained for themselves. Most of whom are now known as prospectors have instead met their demise at the ruins, unaware of many dangers the titans' structures posed. Those who succeed despite those dangers are revered and misunderstood due to their nature: who if not someone with black magic in them can thrive where others fall so easily? The Younger Nations, indeed, are young enough to believe something like that.

I was fascinated with Tyranny's setting: it's a fantasy world where people have only recently discovered ironworking, and where magic, while a point of study, is still an object of fascination due to its mystery. It's the Younger Nations part of Rosa's world, where the "titans" are these hyper-advanced alien people with technology according to Clarke's third law. The scientists of the Younger Nations are struggling to understand how exactly the titans' devices operate, and mostly rely on cargo cultism and superstition to operate the devices with any efficiency.

After the titans have vanished into thin air -- after much thunder and lightning, so to speak -- they left behind a land ravaged with scars. It's an otherwise ordinary terrain -- surreallistically so -- that has many things of odd properties growing on it, similar to Strugatsky brothers' Roadside Picnic. It has ordinary green grass covered in white mold that, upon contact, spreads through the body and shreds the cellular structure as it goes: a continuous necrosis where the victim feels everything until the mold touches the brain. The scars is only one of the dangers a traveler -- or a prospector, for that matter -- has to evade.

So, Rosa is a prospector. She dives into the ruins of the titans and brings whatever she can carry to the scientists of her nation. One day, she takes her gear and moves to the ruins again... and doesn't return the same night.

Next day, by the twilight, she's limping to the city, bruised, beaten and bleeding. The last thing she remembers is trying to crawl into her house, when she loses consciousness...

...and wakes up in the middle of nowhere, with no supplies and a knife as the only tool -- and a flower growing out of where her eye's supposed to be. Amidst the sea of green grass, she has no water, no food and barely a way to orient herself. Without a way to guess which land is closer (the countries are basically circled around what used to be the titan territory, so you're likely to find someone alive if you reach the edge of the continent), she picks north and starts moving.

That's what I've gotten to so far. Truth be told, I'm writing by the seat of my pants, so even I don't know what's going to happen next most of the time.
