I read this book about 15-Oct-2005. I've read this book before. The book is copyright 1930. This note was last modified Monday, 19-May-2014 16:40:11 PDT.
This is book 2 of the "Skylark" series.
This note does not contain major spoilers for the book.
I picked up the new Bison Books (University of Nebraska Press) edition, and got trapped into reading it.
Unfortunately the front matter says nothing about the textual history; I don't know if this matches the original magazine presentation, the hardcover, the Pyramid paperback, or something else. Of course, I don't think there's nearly as much difference between those sources for this volume as there is for the previous in the series.
This seems, from memory, to pretty much match the paperback version I'm most familiar with. Although on page 117, while they're on Dasor, they refer to one of the structures as like a "floating isleport", which I don't remember.
