When the first astronauts of the Mars Colony returned to Earth, they brought a mysterious, metal box they had found half-buried in the red dirt, called the Mars Cube. The scientists assigned to uncover its secrets tested it, scanned it, tried to blow it up, and everything in between. Then they accidentally opened it. Biosafety level-4 laboratories, BSL4, hold the most deadly viruses on the Earth, and Juliet handled them daily. Her research at the CDC landed her a position on the Mars Cube Investigative Team in the world’s only BSL-5 lab.

Seth can only face to the east (or the west, if he tips his head backwards).
