Queen City Jazz

The first 60%: amazing and detailed worldbuilding with really original and fascinating ideas. No real story, to be honest, and the female MC is completely passive (in truth just a witness, never a real factor, always pushed around by others), but the sense of wonder more than makes for that. Loved it. The next 20%: endless and boring introspection and inner MC doubts, plus thick packets of infodump served exactly as infodump: the MC, and therefore the reader, simply receives episodes of explanations from the past. Still no story, too many unintersting and unidimensional SC, and too much jazz references, unfortunately (I love blues but really, really hate jazz)... At 80% i couldn't cope with the slugging boredom anymore and gave up. A hugely wasted opportunity of an amazing scifi world...
