Given the industry demand for sapphic fantasy right now, I was kind of surprised to see this was being self-published, as I thought the world-building, tension, and writing style were easily strong enough to help this book secure an agent and a major publishing house if the author had wanted to go down that road. But I think the authenticity of the attraction that develops between the two leading women attests to the fact that the author did not write the characters this way to tick the right boxes or increase the book's commercial appeal; this was the story she genuinely wanted to tell, and as a result, nothing about it feels forced or inconsistent. Now, to be perfectly honest, it is a very dark and violent book - not the sort that I would usually pick up. We see that the immortal main character is determined to kill herself in the opening pages, as she acquires and tries out a new kind of weapon to see if it might be the thing that can finally end her. Her efforts are graphic, as is the torture she undergoes later, and her particular brand of unkillable-ness spares her none of the pain or damage - it all just heals up afterward. So, if you're sensitive to violence, this probably isn't for you, but I found myself drawn in by Blue's inability to make meaning out of an indestructible life that had long outlived both everyone she had once cared for and the reason she had been made immortal to begin with. What would it be like for the most significant parts of your life to have been lived hundreds of years ago? How well would you even remember who you were, or what you did - especially if you spent much of your time trying to forget? What would atonement look like, if you realized you were ashamed of your distant past, and would it even feel worth pursuing? Is it worth it to love and lose, again and again and again, or is mortality really the only thing that makes life precious and worth living? I really liked how the book engaged with these questions. And for a book that presents a dark version of faith, I appreciated how well it explained that the thing that people were putting faith in, in this particular fantasy world, was unworthy. The story also presented people of no faith as perfectly capable of being just as violent and dangerous in their will to power as people of blind faith, and that feels about right. Of course, I hope human nature, on the whole, is a little less overwhelmingly violent and thoughtlessly tribal as it appears to have become in this world in the wake of the Theocracy, but after a reign like Elo's, who can say? Plus, it is a dark fantasy, so some liberties must be allowed.
