The military--vis-à-vis, the government--races to develop a bio-agent for the creation of super-soldiers, ignoring the axiom: just because you can, doesn't mean you should... The young doctor--a physician/biochemist--sweats profusely inside his BSL-4 (biosafety level 4) suit. But he sweats not because it is hot in the suit; he sweats because of the lethal nature of the biologic agent he is working with. When he has finished, he looks with trepidation at the two glass containers nestled in the case, like twin innocent-looking babies swaddled and quietly sleeping in their cribs. But when awakened, these newborns bring only the promise of death. My God, he thinks. What have I done? Zoey, Kris, Samantha and Lindsay, all twenty-somethings, relax in a famous Las Vegas hotel lounge, celebrating Lindsay's marriage engagement. When Zoey accidently knocks a man's briefcase to the floor, she has no way of knowing she has inadvertently started a deadly pandemic. In the ensuing panic, Kris hears the last words of a dying man: "Get Dr. Tim Gaskin. He will know what to do." In the resulting race to find the mysterious doctor, the girls deal with hordes of walking dead, encountering mental and physical obstacles along the way--and death. Meanwhile, the government also wants to find the doctor, but for nefarious reasons. Can the girls find the doctor and help save Las Vegas, and the planet? Or will the government win out? The ending will shock you; it'll shake you to your core
