Jay had never felt Haile so determined before. It was kind of scary. “Please?” she asked nervously. “What’s happening?”

A torrent of light burst through the window. It was as if a sun had risen over Mirchusko’s horizon. All of space was alive with brilliant efflorescences.

The adult Kiint said: Evacuation enacted.

Designated.

Jay felt a wash of guilty triumph rushing out from her friend. She wanted to reach out and comfort Haile, who she knew from the adult’s reaction was in Big Trouble over something. Instead, she concentrated on forming a beaming smile at the heart of her own mind, hoping Haile would pick it up. Then the air around her was crawling as if she was caught in a breeze.

“Jay!” one of the nurses called. “Come along sweetie, you . . .”

The light around Jay was fading fast, along with the sounds of the ward. She could just hear the nurse’s gasp of astonishment. The breeze abruptly turned into a small gale, whipping her nightie around and making her bristly hair stand on end. Some kind of grey fog was forming around her, a perfectly spherical bubble of the stuff, with her at the centre. Except she couldn’t feel any dampness in the air. It darkened rapidly, reducing the ward to weak spectral outlines. Then the boundary expanded at a speed so frightening that Jay screamed. The boundary vanished, and with it any sign of the ward. She was alone in space devoid of stars. And falling.

Jay put her hands to her head and screamed again, as hard as she possibly could. It didn’t put a stop to any of the horror. She paused to suck down a huge breath. That was when the boundary reappeared out on the edge of nowhere. Hurtling towards her so fast from every direction that she knew the impact would squash her flat. She jammed her eyes shut. “MUMMY!”

Something like a stiff feather tickled the soles of her feet, and she was abruptly standing on solid ground. Jay windmilled her arms for balance, pitching forward. She landed hard on some kind of cool floor, her eyes still tight shut. The air she gulped down was warmer than it had been in the ward, and a lot more humid. Funny smell. Rosy light was playing over her eyelids.
