If you had a warp drive, it would be easy. The mathematics are strange the way ley lines are strange, invisible yet divinable. You’ve pulled your way up sterner mountains, fingertip by fingertip. You’ve already compensated for stellar motion, spacetime curvature, hyperspatial congruences. You’ve scratched out hundreds of equations in cold blue hyacinth ink and piled them away in the knitted stocking under your bed, where only Berenice would think to look. Equations that would tell you exactly where to slice a hole between worlds, if only you had the right knife.

Allen was watching news of the nearest shooting when he decided he needed a tattoo to cover his neck. He had one over his heart, and one on each eyelid. His forehead and cheeks were covered, and enough of his lungs that he might live if he got lucky. He didn’t have the money to ink his back or chest, but he had saved enough for the neck, where more and more people were getting shot these days, he explained to his wife. “More and more people are not getting shot in the neck,” she said, lighting a joint, her eyes narrowing to slits as she dragged.

For as long as I can remember, I have always been two people. My earliest recollection is of myself as a three year-old boy, Danny—and at the same time as a girl of the same age, Cristina. Another early memory is of playing in the rubble of the bomb-ravaged streets of London, when I asked a little boy, “Who will you be tomorrow?” He looked at me as if I were mad. I took it for granted that everyone I met, everyone in the world, was two people like me.

The swan boy lives in an abandoned church in a sleepy, green town by the river. He is small and young-looking still, though he is sixteen now and has been the swan boy for years. His hair is dirty and grown out long enough to cover his shy face. His clothes are striped with greasy white stains, radiating down from the shoulders of his rough shirt. No one would give him a second look if not for the huge, white shield of a swan’s wing that he has in place of a left arm. The people in town do not talk to him.

After Sumé left her last home in ruins, there was no place left to go except back to the island she’d abandoned years ago. Except when her boat scraped against the shallows, she found the island’s dock slumped from rot and disuse. And the path leading from the docks was smothered by vines and ferns, so overgrown it was almost invisible. The stink of stagnant water and algae assaulted her. The emptiness, the neglect confirmed her worst fears. She was the first person to step on the island in twenty years.

I dream again that I am lost in the tunnels of our cities. The fires extinguished, but still a cool blue glow lights my way. The faster I run, the higher I ascend in the city toward the surface, and the light becomes brighter and burns my skin. I fill with knowing, knowing the place where I am going. More and more light fills each room. My skin burns and then becomes darker somehow. And then I am there at the door in the surface, and if I climb through, death and freedom await me. I stand there looking up. Up.
