Contagion

The first book in the spine-tingling Dark Matter trilogy about the frightening effects of a biological experiment gone wrong.

An epidemic is sweeping the country. Almost everyone will be infected. Almost everyone will die. . .

Young teen Callie was one of the rare few to survive the disease after being subjected to the so-called treatment. She was kidnapped and experimented upon at a secret lab that works with antimatter. When she breaks free of her prison, she unleashes a wave of destruction--the contagion.

Meanwhile her older brother, Kai, is looking for her. And his smart new friend Shay may hold the key to uncovering what truly happened--Shay was the last to see Callie alive. The problem is getting past the soldiers at the quarantine zone boundaries.

But even when reunited the teens must find the source of disease. Could Callie have been part of an experiment in biological warfare? Who is behind the research? Is there a cure?
