Story summary.There is a new frontier being opened at the edge of the harsh Martian desert, with settlers that are mostly impoverished from earth & Venus. It's essentially a farming community, with on very big local hazard: "Khom", the "great desert lizard" the size of a small dinosaur that eats crops &, when disturbed, kills people. No one knows how to counter it.
Martin Drake, newly arrived, & prompted by a local beauty, will find a solution to the Khom hazard.
