‘They walked on the thin stony dirt between miles of dead grass too short to bow to the northwest wind. Enormous masses of cloud travelled backward over their heads so that they seemed to be walking very fast, the grey plains sliding with them. ‘Clouds make you dizzy,’ Martin said, ‘like looking up a flagpole.’ They walked with faces upturned, seeing nothing but the motion of the wind. Rosana realised that though their feet were on the earth they themselves stuck into the sky; it was the sky they were walking through, just as birds flew through it.’
