When Dr. Meghan Forester, a young researcher, helps create a vaccine for the deadly Makanza virus, her goal to annihilate the virus is coming true.

Unwittingly, she becomes the poster child for a political movement to free them. But when an old enemy resurfaces, Meghan learns that to save the only man she's ever loved she must pay a steep price.
