Review of Gordian Protocol by David Weber
For those who are impatient, my opinion is that Gordian Protocol is the best time travel novel since the Pliocene Exiles novels by Julian May. If that's all you wanted to know, go read it.
SPOILERS AHEAD!
Don't read on if you don't want spoilers. I'll try not to disclose the plot and story details, but in order to say why I like the book, certain important details need to be dealt with. You have been warned.
Because of the complexity of the ideas on the book, first of all, lets clear up some important points.
1. The book begins with one protagonist dealing with Social Justice issues at his place of work. If you persevere in reading, you will quickly discover that these matters have absolutely nothing to do with the main story and only act to establish the mundane world of our hero.
2. Although this is a time travel story, it is established very early on that the theory and experience of time travel is that you cannot change history, no matter what time travellers do in the past. Thus the main use of time travel is archaeological and for historical research. It also leads to some fairly unscrupulous and immoral activity, which is the first conflict point of the book. This concept of time travel is important to the story as it eliminates the time paradox problems and what in the novel series "Time Wars" was called "time fugue". In other words, I go back and make a change in time to "fix" something I don't like in today's world. Then someone else goes back to prevent my change, and I go even further back to stop their "fix", and they go further back to fix my fix …. ad infinitum. In the world of Gordian Protocol this doesn't work. BUT this all changes when the critical event of the plot occurs and suddenly everything changes although there is still no time fugue. (I won't go into detail).
However, time travel even under this "no effect" status does also have military and criminal implications. The past becomes a limitless hiding and staging place for rebels and criminals. They can go back in time, build up and prepare, move physically to their target location, and then jump back into the present to strike. Obviously, some kind of militarised time force would be needed if the world was one where rebels and terrorists still existed. But note, this force is not a "Time Patrol" in the sense of protecting the "original" history, because as stated above, you cannot change time.
All right. With that covered, what did I like about the book?
First of all I liked the nuanced and well thought out time travel premise. The main characters are historians, not military men (there is an ex-military woman who is a main character), which is a refreshing change from Space Marines or even Time Marines. The time travel machines/ships are interesting and impressive.
Nanite technology plays an important part, both good and bad, and is applied to everyday life as well as having military uses. It actually changes the way things are done, without being "magic".
Due to the changes in the universe of the novel due to the "Gordian Knot" concept of things going very wrong in the time stream, AI is portrayed intelligently both as being good and bad in a nuanced way, and not the usual "AI revolts" idea that is so heavily over used in SF.
The concept of digitising the human mind and personality is also explored in an intelligent and sort of "Altered Carbon" way, but with an interesting social twist.
Unlike many time travel stories, there is a lot of combat between time machines/ships, manoeuvring through both space and time simultaneously. In the military realm, weapons, drones, and even synthetic bodies are used in interesting and sensible ways. If you like military SF (which I do), you will like this book.
There are well written and interesting personal relationships, ranging from romance and friendships, to soul crushing dilemmas and sacrifices on the part of both the good guys and the (nuanced) baddies.
In general I liked the POV of the story told mainly through the eyes of two historians who are forced to become action heroes and a huge and swirling land/time scape.
What did I not like about the book?
The start was a bit confusing due to characters being introduced in several time periods and with one character actually "seeing" two versions of history (including his own life), leading him to think he had a mental breakdown. However once the main story gets going, everything is explained in a satisfactory manner.
Both Russia and China are basically written out of the book's world in a somewhat wish fulfilment manner with the only concession being the use of Mandarin in one character's hybrid language. The entire concept of the Soviet Union is basically wiped out by the military brilliance of the Western powers. It simplifies the world building, and I'm sure satisfies the views of the authors, but I would have preferred to have seen current day Russia and China somehow worked into the world of the future, rather than having Stalin and Mao both conveniently exterminated. On the other hand I did like how Hitler was handled.
So in summary, great book. Read it, especially if you are a fan of military SF and time travel. A very rich back story and no over powered heroes.
