Wow. Where do I start? The writing is genuinely incredible, there's no disputing that. However, the story is hard work. It consists of a lot of violence, sex and there were several times where I had to put the book down and breathe. Having said that, I would definitely recommend this book to anyone who doesn't mind some hard-hitting topics. The subject of immortality had me sceptical at times as the semantics weren't entirely believable, though it truly is an incredible read. Alma Katsu pulls off this story in an unbelievable albeit disturbing way. I don't even know what to do with myself now.
