Maybe 3.5 stars for me, but I'm rounding up because Sascha Stronach has written a great bisexual woman protagonist and cast of diverse characters that I really appreciate.  
I feel complicatedly about this one.  I liked quite a bit about it: original world-building, well-executed weird, and really thoughtful representation.  The system of... magic? science? is interesting and the action scenes are well written.  What didn't work for me at all was the pacing -- sometimes scenes felt like they were drawn out longer than they needed to be, while at other times there seemed to be significant jumps that left me wondering if I'd perhaps missed something.  All in all: reads like a debut, but a promising one; I'll read the sequel.
