I enjoyed and appreciated the unveiling of secret histories both large and huge, and the at-times-great storytelling. I was, however very disappointed by the last 90 minutes with a seemingly-endless rescue mission in flooding tunnels. There are also real issues with the narration, which is split up between chapters rather by characters, so sometimes you have have one character’s words being spoken by the voices of three or more separate narrators, which is utterly confusing and confounding. The quality of the narration varies widely. And, as others have pointed out, there are several places where a chapter ends in the middle of a word! we don’t know whether we have missed a sentence or paragraph or even more. No excuse for that.
