The amazon.com product description:
The alien Catteni invaded Earth and enslaved thousands of humans on the planet Botany, where they struggle to survive while colonizing the world for their overseers. Now that they’ve proved Botany is capable of sustaining life, Kris Bjornsen and her fellow settlers have no intention of surrendering the home they’ve created for themselves…Freedom's Challenge is the third book in this series, following on Freedom's Landing and Freedom's Choice. Interestingly, this is also the book where certain scenes had stuck - vaguely - in my head from the last time I read it, back when the book first came out. Most notably, the scenes on Catten itself. At the same time, I'd forgotten enough of the read that it was like reading the book for the first time.
Armed with the knowledge that the true enemy behind the Catteni is the Eosi race, Kris has begun a campaign to free Botany’s settlers by raising a rebellion among her people against their parasitic oppressors.
Aided by her Catteni lover, Zainal, Kris and the colonists manage to steal warships—and discover dissidents on other Eosi-controlled worlds. If all of the subjugated races join forces, they will have an army large enough to win their freedom and their worlds.
The war of liberation has begun.
One note I have to make - the cover art above is the new art. Honestly in this case I really prefer the original cover art style.
Anyway, this was another book that I ended up racing through while on a camping trip. Loved it. However, I'm having trouble finding a way to describe the story and style without giving a ton of spoilers, or being confusing because by this point, a lot of the storyline really requires knowledge of the previous books in the series.
