An unthinkable act. A family in danger. Their next breath could be their last. The Culpeppers are in Vegas for a vow renewal when missiles from a coordinated terrorist attack streak across the sky, delivering a deadly new chemical weapon that disperses wider and lasts longer than previous generations. It is death in a single breath, with bone-breaking seizures and brain damage from contact with just a drop of the gas. Separated from their family amid the chaos, Jake and Hannah must find their way to each other so they can locate their missing children and Hannah’s mother. No one is safe, and no one knows if they'll all survive Vegas. This is a disaster thriller featuring chemical warfare and how such an event might unfold for the average family. There is some violence and a bit of swearing, but no sexual content.
