Hands down, David Weber is my favorite author. He has the ability to create rich worlds that are complete, logically consisted and interesting. While Weber is mostly known for the Harrington series, which I also really like, I have to say that the Prince Roger books (March Upcountry, etc) are the best military action series that I have read, and that the Safehold series is the best political action series.
Of the two, I actually think that I prefer the Safehold series, although it is a very close match, and I’ll likely change my mind if there would be a new book in the series.
All of that said, this book is actually about the latest book in the Safehold series, which includes Off Armageddon Reef and By Schism Rent Asunder. In a single sentence, I can tell you that Weber has managed to capture my interest all over again. His ability to weave so many concurrent plot lines is the key part of the high level of enjoyment (and quality) that I derive from the books.
The one problem that I have, like the one in the previous one, is stops too early! If I were smart, I would probably drop the series for a decade or so, and wait for Weber to pump enough books out that I can get them all in one shot.
That is not to say that the books are too long, or full of fluff. It is just that Weber is painting a big picture, and that takes time. Unfortunately, it means that by the book ends, I was left with quite a desire to known what the hell is going to happen next.
