A variant of the deadly microorganism that killed over thirty people in Yellowstone National Park surfaces a few months later in Piedmont Springs, a small town in northern Florida. Within a week, eleven people are dead. The talented scientists and FBI agents who solved the mysterious deaths in Yellowstone descend on Piedmont Springs to confront this horrific new outbreak. Led by volcanologist Sage Maldonado and biochemist Whitney Hughes, the team employs state-of-the-art scientific techniques in a desperate attempt to vanquish the microscopic enemy before it spirals out of control. Meanwhile, Piedmont Spring’s residents are confined to their homes by a total lockdown and become more frightened by the day. As the deaths continue to mount, tensions in the once-peaceful enclave escalate to the breaking point. Can Sage and Whitney stop the deadly microbe before it’s too late? The Piedmont Springs Variant is a sequel to The Yellowstone Directive , but it can also be read as a standalone novel.
