Girl Golden Atom – A science fiction tale by Ray Cummings.
Girl Golden Atom – The tale of a scientist who sees a beautiful woman in the atoms of his mother’s wedding ring (and his adventures when he shrinks himself down to join her microscopic world).
This book is actually two stories in one. The stories were originally published as serials in the pulp magazine All Story Weekly. The Girl in the Golden Atom was written in 1919 and its sequel, The People in the Golden Atom, in 1920.
The plot is relatively simple. A man, identified only as the Chemist, discovers a microscopic world inside a golden ring. Soon, he becomes transfixed with a girl he observes there and determines to shrink himself down and find her. He does this by inventing two drugs, one pill to make him smaller and one pill to make him bigger. He then tells this plan to a group of friends, and asks them to safeguard the ring while he is away. Once he returns, he tells them all the story of his adventures inside the world of the ring. After his tale is over, he shrinks himself down again and returns to his love’s side.
