The year is 2456MD, Martian time. Mars Mission Space Center has established a cadet program. Both Lill and her brother, Merak, are accepted. Merak's mission sets off with the science team to explore Neptune and one of its moons, Triton. Merak sees something very unusual on Neptune, but no one believes him! The rumors about Runa, the guardian of Mars, become more of a reality to Lill as she travels alone to the Ocean of Runa. Lill learns that Runa means, "that which is hidden." Mewe, a water cat with webbed feet, is concerned for Lill's safety and follows her to the ocean. While swimming out too far and too deep, they encounter the dreaded Wicky Fish, coming right at them! This cannot be good. Lill's mission encounters a major problem that the Martians must resolve before they can start their trek to planet Zanda in the Andromeda Galaxy. The trip will take them too long to get there, so they must find a solution. What happens next in this galactic fantasy?
