4.5 stars

I loved this way more than I had expected I would! The themes of mental health, religion and power were SO well done. The action scenes were super well-written and nicely balanced out the more introspective, theme-heavy moments of the book.
While the German terms threw me off for a bit at the beginning, I actually came to appreciate them as I read on. Because I understand German fairly well, it was so fun to see why certain characters/places/things were named the way they were; it almost worked like foreshadowing sometimes and I loved being able to see that. That said, I don't think it will hinder your enjoyment if you don't understand German. This book is amazing either way.

The only thing that bothered me was one particular antagonistic character and the way they were portrayed/described... didn't like the fat-phobic language there and I don't think it was necessary.
All the other aspects of the book were 5 star material for me; impeccable character-work, super interesting worldbuilding, engaging plot and immersive writing. Oh, and it's delightfully dark.
So glad I picked this up, will definitely be continuing sooner rather than later!
