Some mistakes can't be engineered away.
What begins as a routine geological survey deep within Valles Marineris quickly spirals into the worst crisis Dave and the humanoids have ever faced.
A violent dust storm cuts them off. Communications fail. Power dies. And the Martian wilderness becomes a threat they can't measure or predict.
With no link to Habitat One and the canyon shrouded in kilometres of dust, the team must rely on skill, instinct and each other to survive.
But when one of their own disappears into the darkness below, the mission becomes something else entirely.
On Mars, the environment is relentless. But the biggest danger isn't out there. It's losing someone you came to Mars with.
Hard science. Dry humour. Engineering disasters. Surprisingly emotional rocks.
Book Four in the Dave & The Humanoids of Mars series.
