Dr. Gregory, a renowned nuclear weapons researcher, is not only dead--he's been charred to a radioactive cinder.
Since this is a death on Federal property, Mulder and Scully are hastily called in. As FBI agents who specialize in unexplained phenomena, they are the investigators of The X-Files, strange and inexplicable cases which are also mysteries that the FBI doesn't want solved.
When a second victim, completely unrelated to nuclear science or Dr. Gregory is obliterated in the New Mexico desert, and then a third dies the same way in Washington, DC, Mulder and Scully begin to focus on the frightening dimension of their task. The bizarre deaths cannot be a coincidence. And as they work to uncover the secret unifying element that unites these deaths, it becomes clear that this twisted puzzle has fatal consequences for the entire world.
The X Files: Ground Zero
Having read all the X Files books available, this one is my favorite. The author real captures the characters and the relationships between them, and the storyline really keeps you hooked.
