Virillion

It was supposed to be a normal Friday. But when an emergency lockdown seals off Helixir-Australia's tallest and most high-tech skyscraper-Anthea McBride and hundreds of others find themselves trapped inside a waking nightmare.

What begins as a chaotic evacuation quickly escalates: fires rage, gunshots echo, and people start collapsing from a mysterious respiratory illness. Some leap to their deaths in desperation. Outside the tower, hospitals fill with patients showing the same symptoms. Dozens are dead. No one knows what the pathogen is-or how it is spreading.

As the government scrambles to respond, whispers of bioterrorism grow louder. Anthea must fight to survive in a building that's become ground zero for a deadly outbreak. But survival isn't the only goal.

Someone has to uncover the truth.

Because whatever was released in Helixir. . . wasn't an accident.
