On the other side of the door, the nature of the rooms changed. They were still clearly in the old tunnels of Ganymede. The walls still had their webwork of mineralized frost, the lighting was still old-fashioned LED housings, and the gray walls showed where ice had melted and refrozen during some climate system glitch years or decades before. But walking through that doorway was walking from the land of the dead into something living. The air was warmer, and it smelled of bodies and fresh soil and the subtle, sharp scent of phenol disinfectant. The wide hall they entered could have been the common room in any of a dozen labs where Prax had worked. Three metal office doors were closed along the far wall and a rolling metal freight gateway hung open ahead of them. Amos and Holden went to the three closed doors, Amos kicking each in turn. When the third flew open, Holden shouted something, but the words were lost in the bark of a pistol and Amos’ return shotgun fire.
The two remaining Pinkwater soldiers who weren’t Wendell scuttled forward, pressing their backs to the wall on either side of the freight gateway. Prax started toward them, but Wendell put a restraining hand on his shoulder. The man on the left side of the door ducked his head into the doorway and then out again. A bullet gouged a streak in the wall where it missed him.
“What can you give me?” Holden asked, and for a moment Prax thought he was talking to them. Holden’s eyes were hard, and the scowl seemed etched into his skin. Then Naomi said something to make him smile, and he only looked tired and sad. “All right. We’ve got a partial floor plan. Through there, we’ve got an open room. It drops down about two meters, with exits to our ten o’clock and one o’clock. It’s built like a pit, so if they’re setting up defense here, we’ve got the high ground.”
“Makes it a damned stupid place to set up a defense, then,” Wendell said.
Gunfire chattered, three small holes appearing in the metal of the freight gateway. The people on the other side were nervous.
“And yet the evidence suggests …” Holden said.
“You want to talk to ’em, Cap?” Amos said. “Or do we head straight for the obvious thing?”
The question meant something more than Prax understood; he could tell that much. Holden started to say something, hesitated, and then nodded toward the doorway.
“Let’s get this done,” he said.
Holden and Amos jogged toward the gateway, Prax and Wendell close behind. Someone was shouting orders in the room beyond. Prax made out the words payload and evac, his heart going tight. Evac. They couldn’t let anyone leave until they found Mei.
“I counted seven,” one of the Pinkwater soldiers said. “Could be more.”
“Any kids?” Amos asked.
“Didn’t see any.”
“We should probably look again,” Amos said, and leaned out the door. Prax caught his breath, expecting to see the man’s head dissolve in a rain of bullets, but Amos was already pulling back when the first shots started.
“What are we working with?” Holden asked.
“More’n seven,” Amos said. “They’re using this as a choke point, but the fella’s right. Either they don’t know what they’re doing, or there’s something in there they can’t pull back from.”
“So either panicking amateurs or something critical to defend,” Holden said.
A metal canister the size of a fist rolled through the gateway, clanking. Amos picked the grenade up casually and tossed it back through the doorway. The detonation lit the room, the report louder than anything Prax had ever heard before. The ringing in his ears redoubled.
“Could be both,” Amos shouted conversationally from very far away.
In the next room, something shattered. People were screaming. Prax imagined technicians like the ones from the previous room shredded by shrapnel from their own grenade. One of the Pinkwater soldiers leaned out, peering into the haze of smoke. An assault rifle blatted, and he pulled back, clutching his belly. Blood poured between his fingers. Wendell pushed past Prax, kneeling by his fallen soldier.
“Sorry, sir,” the Pinkwater man said. “Got careless. Leave me here and I’ll guard the rear as long as I can.”
“Captain Holden,” Wendell said. “If we’re going to do something, we’re better off doing it soon.”
The screaming in the other room got louder. Someone was roaring inhumanly. Prax wondered if they’d had livestock in there. The bellowing sounded almost like an injured bull. He had to fight the urge to put his hands over his ears. Something loud happened. Holden nodded.
“Amos. Soften them up, then let’s head in.”
“Aye, aye, Cap,” Amos said, putting down his shotgun. He took two grenades of his own, pulled the pink plastic strip-pins, rolled the live grenades through the gateway, and scooped his gun back up. The doubled detonation was deeper than the first one had been, but not as loud. Even before the echo faded, Amos, Holden, Wendell, and the one remaining soldier ducked through the gateway, weapons blazing.
Prax hesitated. He was unarmed. The enemy was just beyond the threshold. He could stay here and tend to the gut-shot man. But the image that wouldn’t leave him was Katoa’s still body. The dead boy wasn’t more than a hundred meters away. And Mei …
Keeping his head down, Prax scuttled through the doorway. Holden and Wendell were to his right, Amos and the other soldier to his left. All four were crouched, weapons at the ready. Smoke stung Prax’s eyes and nostrils, and the air recyclers groaned in protest, fighting to clear the air.
