In At the Edge of the Beyond , the first volume of Of Flash and Fiction , science is not a backdrop. It is the engine of unease. This collection of hard science fiction stories draws on real scientific ideas and pushes them into dangerous territory, where observation alters what is seen, systems designed to protect begin to conceal, and breakthroughs in medicine, technology, and artificial intelligence carry consequences no one is prepared to face. Moving from hidden infrastructures to unstable realities and cosmic mysteries, the stories explore the moment knowledge becomes risk and discovery stops feeling like progress. Intelligent, tense, and unsettling, At the Edge of the Beyond is a collection about the human cost of pushing too far, seeing too much, and standing at the threshold of things that cannot be safely understood.
