"Assignment in the Dawn" by Bryce Walton is a science fiction novella written in the mid-20th century, reflecting the style and themes prominent in post-World War II speculative fiction. The story revolves around a future society dominated by a mechanical dictator known as World Brain, which has stifled human individuality and progress in the aftermath of a destructive Atomic War. The likely topic explores themes of identity, freedom versus control, and the consequences of technological advancement on humanity. The plot follows Roland, a man with no memory of his origins, who is awakened by members of an underground resistance—Frances and Berti—in a world where human beings are mere automatons under the rule of World Brain. As Roland learns of his purpose—to help destroy this machine that has stripped humanity of its essence—he grapples with his own existence, questioning what it means to be human. The narrative unfolds as Roland confronts various dangers, including the Martians who wish to protect World Brain in their bid for dominance over Earth. Ultimately, upon completing his mission and destroying World Brain, Roland faces a shocking revelation: he was a construct, created by a more evolved race of mutants, which further complicates his notions of love, sacrifices, and what it truly means to be human.
