How do you protect yourself from a murderer on a planet that wants to kill you? In the four years between the arrival of the first team of colonisers on Mars and the landing of the second team, everything seems to have gone horribly awry. Five of the original colonists have become disillusioned with the mission and each other. The sixth original colonist is dead and it doesn't look like an accident. Now trapped on this planet and chained to the colony for life support, Sadie Blaine and her two teammates must solve the murder before the killer ends all life on Mars.
