This book was recommended in a reddit thread in r/fantasy. It's a free online book so I took a chance and holy crap I loved it. This book is fairly short, more of a novella but it's packed. There's a god-like AI, human immortality and lots to think about what that would actually be like. This book has some pretty graphic sexual violence that can be a turn off but I didn't find them gratuitous. I think it helps shape the reader's understanding of Caroline's mindset after 600 yrs in cyberspace.
