The Kirov Series returns to the Earthforce Story Line as Karpov and company prepare to face down a major Kroth attack, this time, aimed at Earth. In the furor of the battle, Karpov resorts to desperate measures which sends Apollo on a most unexpected journey into deep space. What they find there joins the legion of other discoveries they have made before they finally turn for home.

But something is following them...
