This is a wonderful mix of Germanic culture and high fantasy, and I really enjoyed reading it.
It took me a few chapters to really get pulled in - I've not read any fantasy that has a decidedly German flavour before, and I found it a little jarring. I then spent time thinking that through - why do I find it jarring? I think it is because if that part of Europe is represented, it is often represented as a coal guzzling, industrial revolution style, semi modern context, and to read instead of a regular European flavour fantasy takes effort, but ultimately is very refreshing.
I also really enjoyed the golems. Who doesn't love golems!? It's wonderful to read more books about these mythic creatures, and whilst they are not at all close to the Judaic or Hebrew versions of golem, they bring some sense of that rich culture with them.
A very good, very nicely written tale of redemption, faith, and adventure, about overthrowing a tyrant and pursuing greatness.
Would recommend.

My critisicms are that the conversation between man and God did not have the gravity or depth that one might expect, but it was easily overlooked in the midst of the action!
