For the investigative US Army physician-scientist team of Mickey Peronne, Russell Lange, and Suzanne Coletrane, danger and intrigue hide in every leaning tower as the lines defining friends and enemies become blurred. As the world clock ticks, the race resumes between good and an old evil. Can the evil of the past be again shackled in defeat? If so, what must good sacrifice to ensure it?
