A Taste Of Despair - The Humal Sequence, #2

The Jada-Ko-Vari. A sentient, alien virus-race that infects any storage medium sufficiently large to contain them - computers, ships, even the human brain. Once inside, they control whatever they occupy completely. Their goal is simple. To eradicate humanity. After a brush with the supposed leader of the aliens, James Hamilton and his ship-mates return to human space to find everything seemingly normal.
But normality is something Hamilton has grown wary of over the years. Hamilton knows the aliens, if they have made it to human space, will be almost impossible to stop. Able to access any networked resource and always one-step ahead of him, the aliens are as close to omnipotent as any human god could ever wish to be. To defeat them, he must outwit them. But outwitting the Jada-Ko-Vari will be difficult.
It appeared as if they had already wiped out one species from the galaxy - the great and powerful Humal civilization. Against that kind of overwhelming power, what can one man hope to achieve?
