Deep Freeze by Vicki Hinze

The storm sweeps in like a thief in the night…
Winter storm Holly is the worst in eighty years bringing high winds, subzero temperatures and snowfall better measured in feet than in inches. The weather paralyzes everything in its path, but, in this storm, weather isn’t the only threat.
Emma Miller, a probationary security consultant posing as a reporter, is stranded at Portal International Airport in the worst storm in eighty years. She’s reassigned to protect a top-secret High Containment Lab in the international airport that houses the deadliest bio-contaminate diseases on the planet. A lab under attack by international terrorists who want those pathogens to sell on the black-market.
Dr. Gregory Mason Martin is a bio-containment specialist who runs the top-secret lab, and he knows Emma well. They grew up together, went to school together, and she’s always fascinated him, but she has a long-standing habit of going through men like water, so he’s kept his distance. He doesn’t dare to trust her or her abilities.
Now, all these years later, they must work together to protect the lab and stop the terrorists from obtaining the pathogens. And they must protect the pathogens from Holly, the deadly storm barreling mercilessly toward them. If those pathogens are stolen, the world will be held hostage, and worse, if mishandled, the country could be facing the worst pandemic in history. A pandemic that in short order could wipe out not just cities and states, but the entire nation.
Both are willing to risk their lives. Both are reluctant to risk their hearts. Yet events prove neither of them is who they were thought to be. And a fierce battle against terrorists and the storm proves challenging but no match for the challenges chambered in their human hearts.
