Contagion (Dark Matter‪)‬

You are now under quarantine.

A deadly epidemic is sweeping the country. Twelve-year-old kidnapped experimental subject Callie is one of the first to survive the Aberdeen Flu—unfortunately, she doesn't survive the so-called cure. But something of Callie remains, breaking free and unleashing a wave of destruction. Meanwhile, her older brother, Kai, is looking for her. His new friend, Shay—the last person to see Callie alive—might hold the key to uncovering the truth.

Shay and Kai can't outrun the epidemic. Can they survive it? Can they stop it?

"Exciting, thoughtfully plotted, and featuring accomplished writing, Contagion is a page-turning science fiction treat."—Foreword Reviews
