But even as the mantis died, its whole body lurched forward, pushing through the ring and nearly knocking into the Falcon’s horse. Another mantis leaned in through the opened space, reaching for him, but he seized the reins in a fist and controlled his mount as it tried to rear, then pulled his lash of fire back and cracked it into the second mantis’s face.

On the ground with Kasia, I could barely see anything else of the fighting. I heard Prince Marek and Janos shouting encouragement to the soldiers, and the harsh scraping noise of metal meeting shell. Everything was confusion and noise, happening so quickly I almost couldn’t breathe, much less think. I looked up wildly at the Dragon, who was fighting his own alarmed horse; I saw him snarl something under his breath and kick his feet loose from the stirrups. He threw the reins to one of the soldiers, a man whose horse was sagging with a terrible gaping cut to its chest, and slid down to the ground beside us.

“What should I do?” I cried to him. I groped helplessly for a spell. “Murzhetor—?”

“No!” he shouted at me, over the cacophony, and seizing my arm turned me around, facing the heart-tree. “We’re here for the queen. If we spend ourselves fighting a useless battle, all of this has been for nothing.”

We had stayed back from the tree, but the mantises were herding us towards it little by little, forcing us all beneath the boughs, and the smell of the fruit was burning in my nostrils. The trunk was hideously vast. I had never seen a tree so large, even in the deepest forest, and there was something grotesque about its size, like a swollen tick full of blood.

This time a threat alone wouldn’t work, even if I could have summoned up the rage to call fulmia: the Wood wasn’t going to hand over the queen to save even so large a heart-tree, not now that it knew we could kill the tree afterwards, purging her. I couldn’t imagine what we could do to this tree: the smooth bark shone with a hard luster like metal. The Dragon was staring at it narrowly, muttering as he worked his hands, but even before the leaping current of flame splashed against the bark, I knew instinctively it would do no good; and I didn’t believe even the soldiers’ enchanted swords could bite into that wood at all.

The Dragon kept trying: spells of breaking, spells of opening, spells of cold and lightning, systematic even while the fighting raged around us. He was looking for some weakness, some crack in the armor. But the tree withstood everything, and the smell of the fruit grew stronger. Two more of the mantis creatures had been killed; four more soldiers were dead. Kasia made a muffled cry as something rolled to a thump against my foot, and I looked down at Janos’s head, his clear blue eyes still fixed in an intent frown. I jerked away from it in horror and tripped to my knees, sickened all at once and helplessly: I vomited on the grass. “Not now!” the Dragon shouted at me, as though I could help it. I had never seen fighting before, not like this, this slaughter of men. They were being killed like cattle. I sobbed on my hands and knees, tears falling in the dirt, and then I put out my hands and gripped the widest roots near me, and said, “Kisara, kisara, vizh,” like a chant.

The roots twitched. “Kisara,” I said again, over and over, and droplets of water slowly collected on the surface of the roots, oozing out of them and rolling down to join the tiny damp spots, one after another after another. The dampness spread, became a circle between my hands. The thinnest branching rootlets in the open air were shriveling in on themselves. “Tulejon vizh,” I said, whispering, coaxing. “Kisara.” The roots began to writhe and squirm in the ground like fat earthworms as the water squeezed out of them, thin rivulets running. There was mud between my hands now, spreading and running away from the bigger roots, exposing more of them.

The Dragon knelt beside me. He took up the song of an enchantment that rang vaguely familiar in my ears, something I had heard once long before: the spring after the Green Year, I remembered, when he’d come to help the fields recover. He’d brought us water from the Spindle, then, with channels that dug themselves from the river all the way to our burned and barren fields. But this time the narrow channels ran away from the heart-tree instead, and as I chanted the water out of the roots, they carried the water far away, and the ground around the roots began to parch into desert, mud cracking into dust and sand.

Then Kasia caught us both by the arms and nearly levered us up from the ground, pulling us stumbling forward. The walkers we’d passed in the trees were coming into the clearing now, a whole host of them: as though they’d been lying in wait for us. The silver mantis had lost a limb but still pressed the attack, darting side-to-side and lashing out with spiked arms wherever an opening afforded. The horses Janos had worried about were nearly all down or fled by now. Prince Marek fought on foot, shoulder-to-shoulder with sixteen men in a row, their shields overlapping into a wall and the Falcon still lashing fire from behind them, but we were being crowded in, ever closer to the trunk. The heart-tree’s leaves were rustling in the wind, louder and louder, a dreadful whispering, and we were nearly at the foot of the tree. I dragged in a breath and almost vomited again from the sweet dreadful stink of the fruit.

One of the walkers tried edging around the side of the line, craning its head around sideways to see us. Kasia snatched a sword from the ground, fallen from some soldier’s hand, and swung it in a wild sideways arc. The blade struck the walker’s side and splintered through it with a crack like a breaking twig. It fell into a twitching heap.

The Dragon was coughing beside me from the stench of the fruit. But we took up our chant again, desperately, and dragged more water from the roots. Here close to the tree, the thicker roots resisted at first, but together our spells pulled the water from them, from the earth, and the dirt began to crumble in around the tree. Its branches were shivering: water was beginning to come rolling down the trunk in thick green-stained droplets, too. Leaves were beginning to dry up and shed like rain from above us, but then I heard a terrible scream: the silver mantis had seized another one of the men from out of the line, and this time it did not kill him. It bit off the hand that held the sword, and flung him to the walkers.

The walkers reached up and plucked fruits off the tree and crammed them into his mouth. He screamed around them, choking, but they pressed more upon him and forced his jaw shut around them, juice spilling in rivulets down his face. His whole body arched, thrashing in their grip. They held him upside down over the earth. The mantis jabbed him in the throat with one sharp point of its claw, and the blood came spurting out of him and watered the dry parched roots like rain.
