The Deimos Virus: Target Earth — Leonard D. Hilley II

A devastating virus spreads through the Deimos Station killing fifty-six people. Dr. Carter is somehow immune and the sole survivor. Vowing to avenge the lives of his colleagues and his lover, Carter takes two vials of the contagious lethal virus to Earth with the intention to infect and kill Boyd Grayson, the owner of Grayson Enterprises. He holds Grayson responsible for their deaths. His blind vengeance dismisses the fact that there is no cure, placing the entire world population at risk.
