At least they're primates. That was Commander Riniana Tiana's first thought when she saw the primitive - but sentient - humans of Earth.

And most of them seem extremely jealous of hers! Using the curious custom of clothing, Tiana hides her tail, passes for human and pursues the alien invaders in a desperate struggle to save an ungrateful planet.

King Agesilaus and his Terran Legions have won their first victory against the Median Empire. Despite sustaining heavy casualties, they established a vital foothold in enemy territory.

The K'Tai Imperium invades Agate. On the ground, in the midst of the whirlwind conflict is the Carter family.
