Immunity: An Alexandra Blake Novel

At the start of Andrews's exciting third helix-twister to feature Dr. Alex Blake of the Armed Forces Institute of Pathology (after The Silent Assassin ), DEA agent Ted Silliman suddenly dies in Taos, N.Mex., during a date rape drug investigation. Ted's partner, agent Castro Baxter, disputes the cocaine overdose diagnosis, while Alex suspects a violent hyperimmune response. When Castro and Alex join forces to find answers, they find a connection to a Taos public square fountain, and Alex later learns eight similar deaths occurred locally on the same night. As the death toll climbs, she's determined to stop a potentially serious epidemic. So why does Homeland Security's head, Martin Kincade, oppose her? And could Red Rights, a radical Native American group, be responsible? Andrews, a real-life authority on genetics (The Clone Age ), spikes the chills with a talking DNA computer named Sam and insights into hot-button Native American issues. (Sept.)
