No stranger to balancing an intensely demanding work schedule with the stresses of keeping her family together, AJ Palladino now faces another challenge: she is leaving her young son home with her ailing parents so that she can travel to the site of a new case involving a nuclear power plant in peril. And it will take all her skills to keep her cool while the action and tension build to a fever pitch. Colleton River, a new, one-of-a-kind nuclear facility designed to create medical isotopes with the potential to save millions of lives, has recently been plagued by a series of unexplained mishaps. The accidents have caused the locals to protest the plant, drawing the attention of an anti-nuclear protest group as well as several home-grown terrorists who sense an opportunity to sow fear and chaos.
