"They would face at least two winters here. The howling swirl of dust wrapping them in an ever tighter cocoon. It hadn't been like this at first. No windstorms or unexplained power outages. No sense that the planet itself had begun to speak."The year is 2036, and Project Arche - an international endeavour to create a self-sustaining settlement on Mars - has sent the first wave of civilians to the planet. Silver Antara, Flight Engineer aboard the interplanetary transport ship, Octavia, has spent six months on the inhospitable planet, maintaining a roaming fleet of exploratory rovers looking for signs of water and, potentially, life. Almost thirty-four million miles from home, Silver has learnt to shelter from solar storms and guard against radiation, but when an unexplained accident occurs at the settlement's quarry, followed by the strange disappearance of a colleague, Silver and Chief Engineer Aliyaah Diambu begin to question the behaviour of some of the station's residents and the wisdom of Project Arche as a whole. Are the doubts in Silver's mind just a result of fatigue, or radiation sickness, or is she somehow hearing the planet itself resisting colonisation?
