Pros
+ I love the worldbuilding, especially

the people who choose to live without technology and the credit system that they developed (pebs)

+ I love Mosscap so much. 

Cons
- I don't think this had enough going on to be a separate book. It seems like the author wanted to stretch things out for a third book by

stopping before they reached the City.

-

I think they're setting Mosscap up to die in the next book (Mosscap mentions that repairing the broken part just buys a bit more time) and I'm simply not ready.
