Anger spiked within her. There was no fucking way she was going to let this overgrown malignancy have its way and eat her. Not without giving it a severe case of indigestion.

Ahead of her, black tendrils began to sprout like hair from the surface of the Maw, similar to the tendrils from the Seed. Only these were thick as tree trunks and tipped with razor-sharp tines.

Left! Kira thought, and with a burst of thrusters, the xeno wrenched her down and to the side, away from the lashing tendrils.

She was nearing the center of the Maw. Just a few more seconds …

Next to her, the giant black beak surged upward out of the forest of thrashing limbs and the hills of oozing meat, biting, clacking, and—she felt sure—roaring its silent frustration. Clouds of frozen spittle spewed from within the open mouth.

Kira yelped, and the Seed provided her with one last burst of speed as she bored straight toward the heaving, bleeding, pustulent surface of the Maw. “Chew on this!” she muttered from between clenched teeth.

But in the last moment before she struck, her thought was more prayer than defiance: Please. Please let her plan work. Please could she atone for her sin and stop the Maw. Please could her life have not been in vain. Please might her friends survive.

Please.

4.

The instant Seed touched Maw, a raging howl filled Kira’s mind. It was louder than any hurricane, louder than any rocket engine—loud enough that it gave her pains throughout her skull.

The force of the collision was greater than any emergency burn she’d experienced. Her vision flashed red, and her joints cried out as the bones pressed hard against one another, squeezing fluids, tendons, and cartilage.

How deep the impact carried her and the Casaba-Howitzer, Kira didn’t know, but she knew it wasn’t deep enough. She needed to be near the hidden core of the Maw before detonating the missile.

She didn’t wait to be attacked; she struck outward then, letting loose with the Seed more than she’d ever done before. The Maw was angry. Well, so was she, and Kira gave full vent to her anger, letting every drop of fear, frustration, and grief fuel her attack.

The xeno responded in kind, slashing and cutting like a whirling buzz saw as it burrowed through the surrounding flesh. Gouts of hot blood bathed them, and the howl in Kira’s mind acquired a double edge of pain and panic.

Then the flesh tightened, pressing inward with inexorable strength. Kira fought back, and had the Maw been made of tissue alone, she might have succeeded. But it wasn’t. The cancerous growth was shot through with the same substance that comprised the Seed: a web of black, diamond-hard fibers that moved and spread with ruthless intent, cutting, dragging, constricting.

Where the two xenos touched, they wrestled with fierce contention. At first neither seemed to gain the advantage, so closely matched were they in ability, but then—to Kira’s alarm—she noticed her second skin starting to dissolve into the attacking threads. Alarm turned to horror as she realized the xenos wanted to merge. To the Seed, there was no difference in kind between the part of itself bound to her and the part of itself bound to the Maw. They were two halves of the same organism, and they were seeking to again become whole.
