2018: COUNTDOWN TO APOCALYPSE
Two worlds are locked in mortal conflict. The aliens of the Tenth Planet must harvest Earth's vast resources soon--before their world's elliptical orbit hurls them back into deep space for another 2000 years. If they fail, their species cannot survive the long journey into the void. This is their last chance to avoid extinction.
On Earth, scientists work frantically to stop the huge alien fleet, but even nuclear weapons have only slowed the attackers' dreadful onslaught. Now the ultimate battle for the fate of Earth--and all human life--draws near. And as more powerful weapons are brought to bear, winning the war may be more devastating than the invasion.
