Summary Edit

From the back cover: Eighty years ago, bodiless entities brought a plague of violence and bloodshed to the planet Vulcan. The nightmare ended only when the entities were trapped inside special containers.

Now, on the eve of a galaxy-scale scientific exposition, the containers have been opened, freeing the malevolent entities to possess the minds and bodies of all they encounter, including the crew of the Starship Enterprise. Friends turn into foes, and no one can be trusted, as Captain Picard faces a deadly and insidious threat. Unless the entities can be stopped once more, they will spread their madness throughout the entire Federation.

Information Edit

  • Sequel to Demons.
  • The novel shows Ferengi being subjected to telepathic attacks as well as empathic scans, yet comments from the various TV series make mention that the Ferengis' differing brain-structure makes them immune to such attacks. (However, this was explicitly against Betazoid telepathic influence, which could be a mitigating factor.)
