I loved the Red sister, but Grey Sister is out of this world amazing! Mark managed to capture the dark atmosphere and bring it up to a whole new level. There is literally not a single bad word that I can say about this sequel. Definitely not suffering from middle book syndrome (why do I believe this is a trilogy? don't know...).

All of the awesome characters from Red Sister take centre stage in this sequel and truly come alive. I remember being 100 pages in and struggling to put the book down because it was THAT GOOD! I also love Mark's writing style, he has a unique voice and the ability to summon characters and settings to life, to make you care. I was also impressed by his ability to not only write about girls but also understand them. The world building and magic system are so well done it makes logical sense and drags you into the story and doesn't let you leave. 

As I've already said, there isn't a thing that I can fault this book which is probably my favourite fantasy book of 2018 and of all time. There is no denying that Mark Lawrence is a god!
