I've been wanting to read this book for over a year now, but in my particular way, I waited until I found it in a store, rather than order it (I found it at the excellent, if small, Moonraker Books in Langley, WA on Whidbey Island, by the way)
This book was pretty much what I'd expected it would be and do. I wavered between giving it three or four stars, because I really did enjoy reading it, but I eventually came down on the three star side of the question. I have the feeling that all of the upcoming books in this series will earn such a rating.
The book was rich in technical and historical detail, and did much to advance the storyline of the series from a political standpoint. There was a good amount of cloak and dagger type intrigue, especially earlier in the book. I'm growing on the Irregular warfare group led by Harry Lefferts.
There just wasn't much dazzle or oomph, though. No inspirational moments worth mentioning, and little real challenge to the protagonists' plans. The main focus storylines were the plans to escape from the Tower of London and the USE Navy's relief of Lubeck. Neither ever really seemed like they could do anything other than succeed.
There was never the overwhelming sense of suspense that was done so well with the Croat raid in "1632." Turenne's raid and the ironclad attack on Copenhagen have a little suspense, but everything is just too easy.
The other thing which bothers me is the apparent readiness of a a critical member of each of the antagonist governments (Prince Ulirk of Denmark, The Spanish Cardinal Infante and Sir Thomas Wentworth, Charles I's minister) to consider betraying their governments by supporting the USE in some way. While I know that this will set the stage for the kind of internal intrigue that might make future volumes worthwhile, there was again the sense that this was too easy, and that these individuals arrived at their conclusions without much cultivation. I'd have settled for less about the fledgling Air Force (this from a flying buff!) and more about their conflicts.
Flint has great strength portraying historical characters in their dealings with these new situations, and he should have taken full advantage of this.
All in all, an enjoyable read, and one of completely adequate caliber. I'd love to go back to some more real tense zingers. Leave all the development and technical stuff to the Gazettes and focus on the politics, intrigue and the occasional battle
