Story summary.Three human worlds - Ragnarok, Athena, & Earth. Ragnarokans are the hardy survivors & Athenans the enslaved people of the first book. And three alien races: Gerns, Shomarians, & Kilvar.
Gerns are the slave takers of first book. Now, 3 years after the first book's end, Gern empire is destroyed by humans - led by Ragnarokans.
Action starts with mysterious aliens raiding Ragnarok; they take a 100 women & young men, stun the remaining population of the only town here, & poison the air that blinds all exposed to it. Earth & Athena refuse to help Ragnarok find the culprits & avenge the raid; so Ragnarokans are all alone in their revenge.
Most of the story is Ragnarokans locating the real culprits & taking their revenge, in spite of enemy's far superior strength. Most of kidnapped human will die a horrible death before end. There will be a lot of confusion on who the real culprits are - hominid Shomarians who're related to Gerns, or cat-like telepathic Kilvar.
