Gregor And The Code Of Claw by Suzanne Collins

humans were now fighting on the ground, their bats were executing a full-scale aerial attack on the rats. Mainly they would dive down, rip a clawful of flesh from a rat's backside, and whip quickly back into the air to escape damage to their wings. But Ares was one of a handful of bats with the strength to lift a full-grown rat off of the ground and drop it to its death. Again and again he picked off the deadliest fighters, saving many humans besides Gregor. And as the battle continued, Gregor could hear desperate people begin to call out, "Ares!" hoping for a last-minute rescue from a rat attack. Despite the grim circumstances, Gregor could not help taking satisfaction that his much maligned bond was finally getting some appreciation.
    It was hard to tell how much time had passed — thirty minutes, maybe forty-five — when people began to call, "The nibblers are in! The nibblers are in!" He guessed this meant that all of the nibblers had made it into the tunnel. He'd yet to get a good look at them, so he had no idea what condition they were in. Pretty bad, probably.
    A few minutes later, an order was given to retreat into the tunnel. Ripred took a second out to growl, "Not you, boy!" at him, so Gregor just held his position. This was getting trickier by the moment because he was now up to his knees in bloody ash, and keeping a foothold was harder than ever. Around him, humans and bats carrying wounded began to make for the tunnel. He heard repeated cries of "No torches! No torches inside!" and could only wonder what that was about. Those carrying torches hurled them like javelins into the army of rats, causing some welcome disruption.
    Retreat seemed to be something the humans and bats could execute quickly, because in a matter of minutes, only twenty or so were left defending the tunnel mouth. Then they, too, under the tremendous pressure of the rats, began to slowly fall back. Soon, even the front line, still composed of Perdita, Gregor, Ripred, and the giant man Gregor didn't know, was forced into the tunnel.
    "Fliers, go!" Perdita called. Ares and the last two bats swept across the rat army, peppering them with torches, and then dove into the tunnel.
    Gregor had backed only a few steps into the tunnel when he knew he was going to run into trouble. "Why no torches?" he yelled, but no one had time to respond. Maybe there was some plant in the tunnel that was flammable. Some weird moss or something. The light from the cavern was growing faint. That meant he was going to have to rely entirely on the flashlight taped to his arm to see. He clicked the switch to turn it to high beam and was reassured by the amount of visibility it restored. But what about the others? Ripred didn't need light to fight. He could "see" by echolocation if need be, as could the oncoming rats. Perdita could probably get by on what his flashlight was putting out. But that big guy with the broadsword on the other side of Ripred, he was going to have problems.
    "Retreat! It's too dark for you!" Ripred said to the man, whose only response was a string of curses.
    Gregor yanked his spare flashlight off of his belt and turned it on. "Hey! You on the end!" he yelled. No response.
    "York," Perdita prompted him.
    "Hey, York!" said Gregor. The man looked over and Gregor tossed him the flashlight. "In your teeth!" he instructed. There was no time to tape it to York's arm or even explain what the flashlight was. But York seemed to get the idea. He yanked off his mask, crammed the end of the handle between his teeth, and kept hacking away.
    Somewhere behind him, Gregor supposed, were backup soldiers, but he never saw them. As the rats drove them deeper into the tunnel, all of the light disappeared except the beams from the flashlights. And between handling his own rats and trying to keep Perdita from falling into darkness, there was no time to turn his head. He was still managing, but in this gloom, could it be that some of his confidence was slipping away? A
