The Ascent to Godhood is about the relationship between Hekate, the series' villainess, and Lady Han, a courtesan-turned-revolutionary. It follows how the two met, the times they spent together, and how the relationship fell apart - so, yes, it's basically an f/f villain romance, with delicious intrigue in the background.
The Tensorate is a series of novellas written in unusual formats, some of which worked for me more than others, and when I heard that The Ascent to Godhood was to be a transcription of "a drunken monologue", I thought this wouldn't work for me at all. And was I wrong. You already vaguely know how the story ends, and you're being told by Lady Han what happened, and yet it works - maybe too much? (Those were my FEELINGS, book. How dare you.) It makes up for the details lost in the telling with a narrative voice that you will remember, and maybe exactly because of the few descriptions you're given, the few details you know are even more memorable.
This ended up being my favorite novella in the series.
This is not the story of a revolution. It is much more personal than that, it's a story about love and loss and grief, and it deliberately doesn't focus on Hekate's downfall, because that's not what was important to Lady Han to begin with. Lady Han loved this terrible woman, and hated her just as much, and this is about how those feelings can coexist, and this complicated, twisted relationship. If you're looking for something that is about political intrigue and a revolution, you're going to be disappointed - they're the background, not the focus. I didn't mind that; I was there for the villain romance, and all the conflicting feelings that come with it. It's probably my favorite trope, and it means so much to me to finally see a book focus specifically on an f/f version of it.
Villainous, competent women are my favorite kind of characters, so I knew right from the beginning that Hekate was going to have a lot of potential, but I didn't think I would get a book focusing on her, and I'm so glad this exists. Lady Han is also brave and shrewd and manipulative, and I loved reading her version of the story.
The Ascent to Godhood is a tragedy, one about how your love and admiration for a person can mislead you, and about how the excessive mistrust from those experiences can destroy you all the same. Tragic f/f love stories in which the tragedy has nothing to do with homophobia, like the m/f ones that have existed since forever, have so much value, and while this is a tragic gay story, it's not the kind of tragic gay story we're so familiar with.
I also loved how this novella and The Descent of Monsters were tied to each other. I didn't love The Descent of Monsters, but this novella gave it more meaning. I really recommend reading this even if you, like me, thought the third book was kind of a waste of your time. The only thing I still don't understand is what is even up with Sonami. I mean, this book kind of gave me an answer, but as she's not a developed character at all, I'd still love to know more.
Content warnings: suicide of a minor character, child trafficking, death of a toddler, forced sterilization. Nothing graphic because you're just being told about it, and usually not in detail.
