Mind-Breaks of Space

As Moon Base Alpha is drawn inexorably off course by an intense and inexplicable gravitational force, the Alphans are compelled to contend with hazards that menace their survival as much as the ever-diminishing supply of Tiranium, essential to their life-support system. An uninhabited, glib-talking computer seeking immortality... Two members of an ancient stellar travelling race afflicted with the dreaded Mark of Archanon... A fanatic prone to prescient visions who foresees the imminent destruction of the Moon Base... A race of rebellious androids who want to provoke the Alphans to hate and murder, so they can be programmed to do it themselves.
