“ABSOLUTELY POSITIVELY FABULOUS!”- Amazon Review

When FBI counterterrorism agent Quinn Traynor discovers the first victim of a lethal, unfamiliar virus, he calls CDC epidemiologist Madeline Hamilton. Their investigation reveals an imminent bio-terror attack, and their only hope is to identify the terrorists carrying the disease before it spreads. Every moment counts in their race to prevent a pandemic.

But the ensuing nightmare hits closer to home than they ever anticipated, and one of them will pay an unimaginable price for protecting the country.

“And let’s remember that those charged with protecting us from attack have to be right 100 percent of the time. To inflict devastation on a massive scale, the terrorists only have to succeed once. And we know that they are trying every day.” - Former National Security Adviser Condoleezza Rice
