My first thought upon looking at the cover of Crusade was, “Oh man, this is gonna suck.” It has the word CRUSADE stamped across it in huge letters, with the slogan “Free Holy Mother Terra!” in smaller letters above it. And it’s a collaborative effort. All reasons to expect it to totally suck ass.
So I was very pleasantly surprised to discover that Crusade is, in fact, an enjoyable military science fiction book with a number of engaging characters and a fairly internally consistent world.
The book is set in the 24th century or so, and postulates a future in which humans have fought several large interstellar wars, and have achieved peace with the Orions (sort of like how we fought with the Klingons for years before becoming allies in the Star Trek universe). The Orions are a race of aliens that look vaguely like humanoid cats and have very strict notions of honor (again, like Klingons, but more so). Both humans and Orions have colonized several worlds, and they share border patrol duties.
This universe uses “warp points” to achieve faster-than-light travel. The exact mechanism of the warp points isn’t explained, but they are internally consistent, and we do have to postulate some sort of faster-than-light travel, so I shan’t quibble but shall merely accept it.
The story opens with an Orion fleet with a human aboard intercepting a presumably Terran fleet, which blows up the Orion fleet. The Orions accept that the Terran government did not order the attack (the fleet appears to have come from Thebes, a world that was colonized while the Terrans were still at war with the Orions, and that never got the message that the war was over), but insist on retribution. However, not wishing to precipitate another interstellar war, the Orions transfer the duty of exacting that retribution to the Terrans, leaving the Terrans honor-bound to accept the duty as their own.
I like the realism of the political machinations, in which various politicians, slimy and otherwise, fail to understand the magnitude of their obligation to the Orions, try to weasel out of it, and try to keep the military from doing its job. They start by trying to understand their enemies and negotiate with them, but after a deceitful attack destroys a huge segment of their fleet, they realize that negotiating will get them nowhere, and begin to wage war in earnest.
Oh, and did I mention that the Thebans are religious fanatics who are waging a jihad (yes, that word is used in the text) to liberate Holy Mother Terra, AKA Planet Earth, from the infidels (yes again) who currently hold it? And also, according to the text, it wasn’t until the spike in terrorist attacks in the early twenty-first century that people finally started to accept that the terrorists, rather than the victims, were responsible for the attacks? And did I mention that when the Thebans captured planets, they began programs of forced conversions to their religion, and those who would not convert were killed?
I’ll leave you to read the book for yourselves and find out how the Theban religion got established and why it uses Terran terms like jihad. I’ll also leave it to you to find out how the Terran navy finally gained victory, despite the politicians back home on Earth, and how those same politicians responded to finding out about the atrocities the Thebans perpetrated (I thought that part was well-done and very believable).
And, for those of you who might have been wondering: this book was written in 1992.
