…this novel’s blurb makes my head hurt:

Space travel has always come with risks. But hyperspace travel comes with one particularly frightening risk, namely, the non-corporeal dark energy-based macrobiotic entities that inhabit the void and are drawn to the presence of human minds. Once penetrated by a macrobe, the infected human mind rapidly devolves into raving insanity, which usually presents in a homicidal manner. Fortunately, hyperspace-capable ships are protected by a dark energy resonator that keeps the macrobes away and thereby permits safe interstellar travel.

I think I’ve read enough.
