I had quite a struggle with this one for the first couple of chapters. Shifting between the characters so soon really confused me. However after having read it I really enjoyed it! I liked the characters a lot, they felt very true to me, and had a lot of good chemestry between them. The world itself is super fascinating and I love how it is build. The world reminds me a lot of the world in His Dark Materials, which is near and dear to my heart, but A Darker Shade of Magic still has a lot to it, which is completely unique. Definitely worth a read if you enjoy magic, worlds and how they appear to eachother, brilliant characters and the solving of a quest! :) 
 4/5 stars from me! :)
