0Sparks fly as Dr. Lily Robinson-the brilliant academic pathologist and covert assassin for the U.S. Government-investigates two seemingly unrelated deaths alongside her lover, Agent Jean Paul Marchand, and D.C. Medical Examiner Dr. Logan Pelletier.

A U.S. Senator and the president of a developing nation are found dead in their beds. As governments thousands of miles apart react to the fallout and begin their investigations, no one claims responsibility, and no motives are clear.
