The Darkness on Diamondia

Colonel Martin was sent to Diamondia to report on the war between Earth-descended colonists and the guerilla warriors of the inhuman Irsk. Because something was going terribly wrong -- a darkness was setting in, mental confusion was epidemic, and there was evidence of Outside interference. The Darkness was impartial, and Morton's encounters with it were the most disturbing events of his career. For it seemed as if the Outside were deliberately stirring up the planetary pot, mixing minds with minds, and personalities with personalities. But when Morton realized that the only solution might be to find and use the incalculable power of the Lositeen Weapon, he realized also that the decision was too great for any one man -- even for all men together -- to make. A brand new novel from the Slan-man, A. E. van Vogt himself...with all of van Vogt's mind-shaking fireworks and narrative mastery.

Beyond its central premise, the book can be read through the connected lenses of Fiction. Those themes offer useful points of attention as the characters, ideas, or world develop, especially where the book complicates the expectations of its primary category.
