Bound By Flame may be set in a familiar universe but it follows a story arc and character I haven't explored before. I'd suggest you read Flame in the Veins before reading this book to avoid spoilers for FitV, but as this book is a standalone, you don't have to.
I also made the book cover myself, just saying. That's why it looks a little rough. I did it in Procreate and I had no idea what I was doing, but I think it fits the story.
