The phone call isn?t the first threat Dr. Alexis Morgan has received. Not by a long shot. It is, however, the first time she escaped the taunting voice only to find her neurobiology lab at the University of North Carolina being raided. Alexis thought she and her husband, Mark, were finally moving beyond the horrors of the Monkey House, sight of the notorious, top-secret drug trials for a powerful personality-altering drug that stole so many innocent lives? But now Alexis's research into the drug's effects has caught the attention of a shadowy government agency anxious to use the drug for its own nefarious purposes. When people begin dying, Alexis knows it is only a matter of time before the men behind the conspiracy try to silence her. She and Mark flee into the mountains of North Carolina, seeking refuge with the other survivors from the Monkey House. There, as government agents close in, the survivors must also battle the demons within their own minds if they hope to keep the drugs out of enemy hands.
