Catching Fire

an enemy. But when he sees the wall of fog, he tosses a still-sleeping Mags onto his back and takes off. Peeta is on his feet but not as alert. I grab his arm and begin to propel him through the jungle after Finnick.
    “What is it? What is it?” he says in bewilderment.
    “Some kind of fog. Poisonous gas. Hurry, Peeta!” I urge. I can tell that however much he denied it during the day, the aftereffects of hitting the force field have been significant. He’s slow, much slower than usual. And the tangle of vines and undergrowth, which unbalance me occasionally, trip him at every step.
    I look back at the wall of fog extending in a straight line as far as I can see in either direction. A terrible impulse to flee, to abandon Peeta and save myself, shoots through me. It would be so simple, to run full out, perhaps to even climb a tree above the fog line, which seems to top out at about forty feet. I remember how I did just this when the muttations appeared in the last Games. Took off and only thought of Peeta when I’d reached the Cornucopia. But this time, I trap my terror, push it down, and stay by his side. This time my survival isn’t the goal. Peeta’s is. I think of the eyes glued to the television screens in the districts, seeing if I will run, as the Capitol wishes, or hold my ground.
    I lock my fingers tightly into his and say, “Watch my feet. Just try to step where I step.” It helps. We seem to move a little faster, but never enough to afford a rest, and the mist continues to lap at our heels. Droplets spring free of the body of vapor. They burn, but not like fire. Less a sense of heat and more of intense pain as the chemicals find our flesh, cling to it, and burrow down through the layers of skin. Our jumpsuits are no help at all. We may as well be dressed in tissue paper, for all the protection they give.
    Finnick, who bounded off initially, stops when he realizes we’re having problems. But this is not a thing you can fight, only evade. He shouts encouragement, trying to move us along, and the sound of his voice acts as a guide, though little more.
    Peeta’s artificial leg catches in a knot of creepers and he sprawls forward before I can catch him. As I help him up, I become aware of something scarier than the blisters, more debilitating than the burns. The left side of his face has sagged, as if every muscle in it has died. The lid droops, almost concealing his eye. His mouth twists in an odd angle toward the ground. “Peeta —” I begin. And that’s when I feel the spasms run up my arm.
    Whatever chemical laces the fog does more than burn — it targets our nerves. A whole new kind of fear shoots through me and I yank Peeta forward, which only causes him to stumble again. By the time I get him to his feet, both of my arms are twitching uncontrollably. The fog has moved in on us, the body of it less than a yard away. Something is wrong with Peeta’s legs; he’s trying to walk but they move in a spastic, puppetlike fashion.
    I feel him lurch forward and realize Finnick has come back for us and is hauling Peeta along. I wedge my shoulder, which still seems under my control, under Peeta’s arm and do my best to keep up with Finnick’s rapid pace. We put about ten yards between us and the fog when Finnick stops.
    “It’s no good. I’ll have to carry him. Can you take Mags?” he asks me.
    “Yes,” I say stoutly, although my heart sinks. It’s true that Mags can’t weigh more than about seventy pounds, but I’m not very big myself. Still, I’m sure I’ve carried heavier loads. If only my arms would stop jumping around. I squat down and she positions herself over my shoulder, the way she rides on Finnick. I slowly straighten my legs and, with my knees locked, I can manage her. Finnick has Peeta slung across his back now and we move forward, Finnick leading, me following in the trail he breaks through the vines.
    On the fog comes, silent and steady and flat, except for the grasping tendrils. Although my instinct is to run directly away from it, I realize Finnick is moving at a diagonal down the hill. He’s trying to keep a distance from the gas while steering us toward the water that surrounds the Cornucopia. Yes, water, I think as the acid droplets bore deeper into me. Now I’m so thankful I didn’t kill Finnick, because how would I have gotten Peeta out of here alive? So thankful to have someone else on my side, even if it’s only temporarily.
    It’s not Mags’s fault when I
