One man holds the cure to a mutant strain of the Eke virus—one of the most deadly of all. And for the sake of money and power, he’s holding the whole world hostage. But there’s an even greater problem: No one knows if the cure will work. Now virologist Dr. Celeste Braun must turn her scientific skills to the art of investigation–by solving the crime and finding the cure.

B.B. Jordan is the nom-de-plume of Frances Brodsky, Professor of Cell Biology and Director of the Division of Biosciences at University College London. She is a bench scientist recognized for her elucidation of basic cell functions that influence human metabolism and the immune system. Her writing is inspired by a love of science and a desire to communicate the scientific enterprise to the general public and humanize the process of scientific research. In addition to PRINCIPAL INVESTIGATION, B.B. Jordan is the author of the two mysteries, SECONDARY IMMUNIZATION and TRIPLET CODE, both featuring the brilliant virologist Dr. Celeste Braun.
