Invaders

They came from the brightest star in the southern constellation of Carina. First they studied us. Now they're among us, threatening human existence as they search for the Starcore, the greatest device of the lost Polarions. Logan is captured in the Nevada desert but escapes in Greenland. There he finds an extraterrestrial stealth ship, giving him the means to take the battle to the enemy.

Kazz is a genuine Neanderthal and Philemon is an apish proto-human, two thugs with priceless information to sell to the highest alien bidder. But first they have to get off this backward planet. They hijack Logan's Guard ship, needing it to crack an ancient alien structure at the bottom of the Arctic Ocean, believing it will provide them the ticket out of here. What they don't know is that the structure holds a terrifying alien prisoner that could doom the human race to eternal servitude - and if they did know, they wouldn't care.

The Galactics quarantined Earth. But the last Guard agent died. Logan found his stealth ship, and now it's his job to enforce Galactic law against alien predators. Lord Beran the Antaran regards humans as little better than insects to stomp if they get in his way. He's searching for the lost Polarions, last seen on this backward planet thousands of years ago. There are alien relics hidden under the ice sheets of Greenland and Antarctica. Lord Beran wants those, even if uncovering them will unleash a stellar holocaust.
