Vulcan’s Hammer

Set after a devastating world war, when the 70 nations of Earth form the Unity Party cede global governance to the Vulcan AI system, which algorithmically dictates policies for Unity to carry out. But after Vulcan is attacked and a special agent is murdered, Unity director William Barris is called to unravel the mystery to figure out who — or what — wants to destroy the system to which he has dedicated his life.
