The Long Earth

children, and went back for their own old folk, and their elderly neighbours. In care homes, some bewildered senior citizens had Steppers slapped on them and were sent East or West for the first time in their lives. In the schools, teachers carried over their students, and big kids carried little kids. In the hospitals the staff and the healthier outpatients found ways to lift and step the heaviest, most immobilized patients, even coma victims and babies in incubators, and went back for more, and then waited as surgeons hurried to close up interrupted operations, and carried those patients over too. All across Madison, the majority of humanity who could step aided the minority who couldn’t. Even extreme phobics like Rod Green who couldn’t tolerate a single step were met by medics who did their best to stabilize them, until they could be hurried away from the danger zone and taken back to the Datum.
    In Madison West 1, Monica Jansson watched the results unfold. There were TV cameras all around the area, and eye-in-the-sky images relayed down from drone aircraft. For Jansson, it felt very odd to be
safe
in such a crisis, but the medics had taken away her Stepper, and there was nothing more she could do. So she watched. Somebody even brought her a cup of coffee.
    From the air, here in West 1, you could clearly see the lakes, the isthmus, the distinctive geography of the area laid out like a map, a twin of the region on the Datum, a twin that had been entirely un inhabited two decades ago. Madison West 1 had started to make its own mark in this world, with swathes of forest cleared and marsh drained, and some tracks wide and metalled well enough to be called roads, and clusters of buildings, and steam and smoke rising from the mills and forges. But today the inhabitants of West 1 were scrambling to accommodate and help the incoming, fleeing from the Datum.
    Here they came. Jansson saw them emerge, one by one or in little groups. There were even some in the lakes, steppers coming over from their boats or their surfboards. Rowboats cut across the bright blue waters to each waving speck.
    And, on land, as the steppers crossed, Jansson saw a kind of map of the Datum city emerge on the green carpet of West 1. There were the university students, a multicoloured blur that marked the location of their campus, stretching south from the shore of Mendota. There were the hospitals, St Mary’s and Meriter and the UW Hospitals and Clinics, little rectangular huddles of doctors and nurses and patients. There were the schools, teachers with their charges where their classrooms should have been. On the Monona shore the contents of the convention centre appeared, business types, in flocks, like penguins. The area around Capitol Square itself started to fill in, the diamond shape of the square, with the shoppers and diners from State and King lining up along the tracks of the streets leading off to west and east, and the office workers and residents of East and West Washington. It was indeed a map of Madison, she realized, a map made up of the people, with the buildings stripped away. She looked for Allied Drive, where a group of nuns stepped across realities from the Home, with the vulnerable children in their charge.
    And in the very last second, she saw, in a view from ground level, that where the high-rise buildings of downtown stood, people started appearing in mid-air. Many were in business suits. They just stepped over from the upper floors because there was no time left to get to the elevator or the stairs, or do anything else. Three-dimensional ghosts of the doomed buildings coalesced, ghosts composed of people who seemed to hang in the air, just for an instant, before falling to the ground.
    Somewhere near Jansson, a Geiger counter started clicking.

    JOSHUA AND SALLY hurried through the last few Madisons, West 10, 9, 8 … Joshua wasn’t interested in these crowded worlds; all he wanted now was to get home. 6, 5, 4 … In one Low Earth they had taken the time to cross geographically, from Humptulips to Madison, flying the airship on the one engine Franklin Tallyman, boy genius of Reboot, had managed to fix up for them. 3, 2, 1 … There were barriers in the last few worlds, some kind of system of warning signs; they hurried on—
    Zero.
    Madison was gone.
    Joshua stood in shock, gasping. Sally clutched his arm. They stood in a plain of rubble. Gaunt shapes, fragments of wall sticking out of the ground. A few twisted
