Set in a distant future, after the invention of faster-than-light space travel has propelled a still-immature mankind into the far corners of the Milky Way, the novel features creatures of immense variety--amoebas that cover entire worlds, sensual females that feed on substances from their males' reproductive systems, talking reptiles, and other creations drawn from the classics of Cuban and international science fiction--all of which serve as colleagues, fellow adventurers, sex partners, teachers, or members of the military high command in the Galactic Community governing this part of the universe. Our protagonist, Jan Amos Sangan Dongo, has a special role in this otherworldly menagerie: He is a veterinarian who specializes in treating enormous animals across the galaxy. When a colonial conflict threatens the fragile peace between the Galaxy's seven intelligent species, Dr. Sangan must embark on a daring mission to enter a gigantic creature and find two swallowed ambassadors--who also happen to be his competing love interests.
