Zarlah the Martian

The narrator describes unexpectedly establishing communication with a Martian named Almos and learning about Martian civilization, its health-giving light rays that prevent disease and aging, social reforms that eliminate crime, and technologies such as virators and aerenoids enabling long life and rapid space travel. A romantic attachment to Zarlah prompts hazardous journeys between worlds, including high-speed aerial voyages, a race to an observatory, perilous passage through lunar environs, and dramatic accidents. The narrative alternates explanatory accounts of Martian society and inventions with tense travel episodes and personal confession, ending in catastrophe and reflection on the costs of interplanetary contact.
