I read this book about 11-Aug-2004. I've read this book before. The book is copyright 1965. This note was last modified Monday, 19-May-2014 16:39:17 PDT.
This is book 4 of the "Skylark" series.
This note contains spoilers for the book.
Triumphant final book of the series; and one of the very few known examples of a "late sequel" (this particular one came 30 years after the preceding material) that works. This is arguably the justification for the whole series -- and it was really pretty well wrapped up at the end of Skylark of Valeron.
DuQuesne finally figures out that ruling Earth isn't for him. I wonder if anybody could do the story of his founding of his empire? I guess David Weber -- at least, he's gotten away with founding or at least re-founding empires with absolute power before.
