What is the name of the book or author in which:

The action for this book occurs on a human colony world, not Earth itself.

Interstellar human civilization has been enslaved by an alien race. The alien race is reptilian (although superficially very similar in description, these are not the Aann of Alan Dean Foster's Universe). The reptilian race is faster & stronger than humans. I kinda think their race name begins with an 'R' but think I might be confusing it with the Ryall of Antares Dawn series.

Some human soldiers were genetically, chemically, cybernetically, and trained to be super soldiers to take down the reptilians in one-on-one combat. Humans lost the war long enough ago that the remaining super soldiers are old men now. They have been training other humans to fight the lizard aliens in secret - but without the advanced technology, these trainees can only hope to lose more slowly to the alien soldiers.

Also before its fall, humans cached 9 battlecruisers in a last ditch tactic to surprise and slow down the alien advance by reactivating them behind the reptilian lines. Unfortunately for humans, the aliens advanced far too fast to use this stratagem.

During the course of the book, humans on the colony world (on which the action takes place) discover that the reptilians are also in a war with another race (I think they were butterfly shaped but could be wrong). Humanity decides to activate the battlecruisers and get them to this alien race (in an "enemy of my enemy" gambit). Much of the book is about trying to get those 9 cached battlecruisers to this third (butterfly? shaped) race.

I probably read this book before the mid '90s.

  • @cde Other than interstellar humanity fighting a losing battle, how does this resemble Battlestar Galactica?

This is the Blackcollar trillogy by Timothy Zahn. The alien race is called Ryqril.

Sounds like book 1. Here it is on Amazon

  • This sounds very very likely to be correct. I'm trying to find a better synopsis to confirm.

  • Yes, I found a detailed synopsis and I wanted to know the name of the book because I was hoping for a sequel. There is!

Although this already has an accepted answer, here is some more information that may be of use to future searchers.

The first novel of the series is called The Blackcollar. Following is its summary from goodreads.com:

Blackcollars were a human task force designed to defeat alien Ryqril invaders. The guerilla warriors were improved by drugs to enhance lifespan, speed, reflexes, and memory. Allen Caine has never met this weapon, stronger than Nova-class battle cruisers, but 30 years later goes to find their remnants, Damon Thane, and 5 starships from the planet Plinry.

It was followed by The Backlash Mission. Here's its GoodReads summary:

Blackcollars are a human task force designed to defeat alien Ryqril invaders. Backlash, the drug that improves their lifespan, speed, reflexes, and memory, has been all used up. Allen Caine and the Blackcollars seek the formula in the Aegis mountains, near Denver Colorado, deathtrap center of enemy territory.

The final book is called The Judas Solution. Again, from GoodReads:

Damon Lathe, Allen Caine, and the Blackcollar drug-enhanced combat team want to infiltrate a Ryqril-conquered colony, a tactical center where the whole sector's military data flows through against the Chryselli. But Ryqruil Prefect Jamus Galway of Plinry has a clone duplicate of Allen ready.

  • If so desired, it is acceptable to edit another's answer to add details to it.
