Only when Marlo and her mother have followed the attendants through the faux-marble foyer and into the room filled with diffusers and soft jazz and laid down on the massage tables covered in crisp, clean-smelling sheets; only when someone has placed a cool gel pack over Marlo’s eyes and set something against her skin that starts kneading, a familiar, needling motion that ignites a distant spark of recognition within her; only then does Marlo understand where her mother has taken her. She pushes back her eye mask and sits up.

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.

In the beginning, we are one, and we are ignorance. Our skin is chaffed tender from the womb-sac and the exit ring. Out, we writhe blindly in the grit that cuts our softness until the dryness of the air hardens us. Slowly, receptors awaken. Muted colors curve across the night, outlining the glistening ribs of the drop chamber arcing over us like planetary rings. Instinctually, we grope through the hard stillness. Our tac-pads draw against lines of unmoving flesh, cold like a memory of interstellar vacuum. A dome of skin radiates faint warmth.

“Ever consider killing yourself?” the gecko said. “It’ll save you one hundred percent on your car insurance.” I was alone, but not. I tried to step on the creature, but my foot wasn’t there. I clenched my teeth, which felt like water. Alleyah’s Southie accent crackled a reminder of radio. “Tracey, are you paralucid yet? Need another poke of DMT?” I was back in high school—or somebody’s high school. The classrooms were vintage Sears catalogs and a spruce tree that grew sideways—not in a directional sense but just with a profound association with the concept of sideways. I climbed the tree and then fell.

It took twice as long to get to the third deck from the first as it did to get to the first deck from the fifth. Alice was quite certain there was no mechanism in existence capable of adding fractional decks to the ship, and so was chalking this up to another aspect of the ongoing computer malfunction. She supposed a way to validate this was to ask that the elevator stop at, say, deck two-and-five-sixteenths, but she also didn’t want to encourage the computer’s departures from reality any more than necessary.

Things began to go badly for the crew of the USFS Erwin around the time Dr. Marchere’s coffee mug spontaneously reassembled itself. Dr. Louis Marchere was not, at that moment, conducting some manner of experiment. Well, he was, only not on entropy and the nature of time. He was running several other tests, of the kind that make perfect sense on a scientific vessel such as the Erwin. About half of them were biological in nature, concerning how small samples of cellular material react to certain deep-space factors.

Start with a romance: a man and a woman who are wildly and irrevocably in love with each other. Or two men. Or two women. Or two people, because life is beautiful and complex. Just know that these Lovers are important. The fate of the galaxy rests on their shoulders—because, of course, the fate of an entire portion of known space can be determined by two people in love. The laws of physics are remarkably vulnerable to the laws of love.

The year I turned five, my father got taken out by a giant robot. I was present and I took it very personally. You honestly don’t expect that kind of thing when you’re a kid, not even if you’ve seen the giant robot from a distance every day of your life and have been taught what random carnage the giant robot got up to. I had grown to that tender age knowing that the giant robot killed people at the rate of one a day.
