A Tragic Accident or a Suicide Mission? In the year 2012, Valkerie Jansen, a young microbial ecologist, is presented with an amazing opportunity to continue her research as a member of the NASA corps of astronauts.

When a sudden resignation opens the door for her to be a part of a mission to Mars, her life dream becomes a reality. Dreams turn suddenly to nightmares for NASA and the crew as an explosion cripples the spacecraft on the outward voyage. The crew's survival depends on complete trust in one another-but is one of the four the saboteur?
