Nice review, thanks for sharing it!
I just finished my own.
I really loved the Breen and Gorn's portrayal in this book. The Typhon Pact is already showing its fraying nature yet, ironically, the Federation may be shoring it up as I see a relationship with the Gorn and Romulans lasting far longer than I see the Breen with anyone. Well, you know, ignoring a certain EVENT in three years.
I actually feel bad for the Romulans for the first time in, well, forever. It may be wrong but I'm also getting the impression the Breen are a very fiscally conscious government given everyone is always speculating on their budgets whenever they propose projects. It's a nice change of pace from most governments I know. I do wonder, however, whether there's any positive qualities to the Breen or whether they're just a loathsome dictatorship. Could you share what you see as the positives of Breen society, DM?
I also agree with fans on this board who state they think the Breen sacrificed much better assets than they would have gained with the wormhole ship. As impressive as that was. Also, bluntly, I can't imagine the Tholians will be too happy to be betrayed to the Federation by the Breen. Jeez, these guys are awful allies.
Great book and awesome spy fiction.
