J. A. Roni Sr. is a writer familiar to domestic readers mainly from his fascinating dilogy about the life of prehistoric people, “The Fight for Fire” and “The Cave Lion.” However, for science fiction lovers, this author is, first of all, one of the founders of science fiction, equal to Jules Verne and H.G. Wells, in whose works, almost for the first time in the history of science fiction, the theme of interplanetary travel arose, and the theme of global cataclysms befalling the Earth - and much more another, which has become a classic of the genre these days. Here is the best of the creative heritage of Roni Sr. - a writer, without whose books science fiction would never have become what we know it!
