She's close enough to see limbs now, attenuate sticklike things slapping the surface of the lake into a local frenzy. Almost as though the rifter ahead is a poor swimmer, in over his head and panicking…

"He's alive," she buzzes. The deadman icon pulses, contradicting her.

"No," Lubin says.

Only fifteen meters away now, the enigma erupts writhing from the surface of the Lake in a nimbus of shredded flesh. Too late, Clarke spots the larger, darker shape thrashing beneath it. Too late, she resolves the mystery: meal, interrupted. The thing that was eating it heads straight for her.

It can't b—

She twists, not quite fast enough. The monster's mouth takes the squid with room to spare. Half a dozen finger-sized teeth splinter against the machine like brittle ceramic. The squid torques in her hands; some sharp-edged metal protuberance smashes into her leg with a thousand kilograms of predatory momentum behind it. Something snaps below the knee. Pain rips through her calf.

It's been six years. She's forgotten the moves.

Lubin hasn't. She can hear his squid bearing in, cranked to full throttle. She curls into a ball, grabs the gas billy off her calf in a belated countermeasure. She hears a meaty thud; hydraulics cough. In the next instant a great scaly mass staggers against her, batting her down through the boiling interface.

Heavy water glows on all sides. The world is fuzzy and whirling. She shakes her head to lock it into focus. The action wavers and bulges overhead, writhing through the shattered refractory surface of Impossible Lake. Lubin must have rammed the monster with his squid. Damage may have been inflicted on both sides—now the squid's corkscrewing down into the lens, riderless and uncontrolled. Lubin hangs in the water facing an opponent twice his size, half of it mouth. If there are eyes, Clarke can't make them out through this wobbling discontinuity.

She's slowly falling up, she realizes. She scissor-kicks without thinking; her leg screams as something tears it from the inside. She screams too, a ratcheting torn-metal sound. Floaters swarm across her eyes in the wake of the cresting pain. She rises from the lake just as the monster opens its mouth and—

—holy shit—

—disconnects its jaw, right at the base, the mouth dropping open way too fast and suddenly it's closed again and Lubin's just gone, nothing to suggest where he went except the memory of blurred motion between one instant and the next.

She does perhaps the most stupid thing she's ever done in her life. She charges.
