"What's that?" A row of bright dots, evenly spaced, has just moved onto the screen.

"Surveyer's stakes." Another row marches into range behind the first. "For the geothermal program, you know?"

"How about a quick drive-by? I bet those generators are pretty impressive."

"I don't think the generators are in yet. They're just laying the foundations."

"It'd still make a nice addition to the tour."

"We're supposed to steer clear. We'd catch royal shit if anyone's out there."

"Well?" That smile again, more calculated this time. "Is there?"

"Probably not," Joel admits. Construction's been on hold for a couple of weeks, a fact which he finds particularly irritating; he's up for some fairly hefty contracts if the Grid Authority ever gets off its corporate ass and finishes what they started.

Preteela looks at him expectantly. Joel shrugs. "It's pretty unstable in there. Could get bumped around a bit."

"Dangerous?"

"Depends on your definition. Probably not."

"So let's do it." Preteela lays a conspiratorial hand briefly on his shoulder.

Ceratius noses around to a new heading. Joel kills the bait lights and cranks the sonics up for one screeching, farewell burst. The monsters outside — those that haven't already retired gracefully, their tiny fish brains having figured out that metal is inedible — run screaming into the night, lateral lines burning. There's a moment of surprised silence from the cargo. Preteela Someone steps smoothly into the gap. "Folks, we're taking a small detour to check out a new arrival on the rift. If you tap into the sonar feed you'll see that we're approaching a checkerboard of acoustic beacons. The Grid Authority has laid these out in the course of constructing one of the new geothermal stations we've been hearing so much about. As you may know, similar projects are underway at spreading zones all the way from the Galapagos to the Aleutians. When these go online, people will actually be living full-time here on the rift—"

Joel can't believe it. Preteela's big chance to scoop the library and she ends up talking exactly like it does. He quietly aborts a midbrain fantasy he's been nurturing. Try to get into fantasy-Preteela's jumpsuit now and she'd probably start reciting a cheery blow-by-blow.

He switches on the external floods. Mud. More mud. On sonar the grid crawls towards them, a monotonous constellation.

Something catches Ceratius, slews it around. The hull thermistor spikes briefly.

"Thermal, folks." Joel calls back over his shoulder. "Nothing to worry about."

A dim coppery sun resolves to starboard. It's a torch on a pole, basically, a territorial marker beating back the abyss with a sodium bulb and a VLF heartbeat. It's the Grid Authority, pissing on a rock for all and sundry: This is our hellhole.

The line of towers stretches away to port, each crowned by a floodlight. Intersecting it, another line recedes directly ahead like streetlights on a smoggy night. They shine down on a strange unfinished landscape of plastic and metal. Great metal casings lie against the bottom like derailed boxcars. Teardrop ROVs sit dormant on flat plastic puddles frozen harder than basalt. Sharp-edged conduits protrude from those congealed surfaces like hollow bones sawn off below the joint.
