For Ross, who is not the robot
Part One
CHAPTER ONE
Many years later Cat still remembered the damp twilight on her skin and the way the dewy grass prickled and snapped beneath her bare feet as she ran up to the edge of the forest that surrounded her childhood home. Her mother had let her stay out late that night so she could catch fireflies in a jar, and she lay amongst the tumbling honeysuckle and ropes of wild grapevines with the jar held aloft, holding still and waiting for the fireflies to buzz through the opening so she could trap them inside.
As the night fell soft and sparkling all around her, Cat watched the fireflies climb up the sides of the glass, the glow of their abdomens transforming them into intermittent stars. Somewhere around the front of the house a car door slammed, once and then twice, but she ignored it, knowing her father to come home late from his meetings in the city.
But then the light came on in the screened-in back porch. Immediately, Cat slunk down into the shadows. She was at an age where she liked to spy, where she liked to note undetected the goings-on of adults. The round, familiar silhouette of her father stepped onto the porch, followed by another figure, tall and thin and angular, a figure Cat didn't recognize. She clutched the fireflies to her chest and crept around the perimeter of the yard to get a closer look. Those fireflies she hadn't caught blinked on and off in the darkness, and Cat's jar glimmered faintly from between her hands. On the porch, behind the gauzy screen, the unfamiliar silhouette sat down. Her father leaned over it, their shadows blurring together. Cat slid across the grass. She crept up to the porch, near the steps, to the place where the screen had been ripped away from the frame a few weeks ago by the old raccoon that came around the yard sometimes. She tucked the jar under her arm and stood on her tip-toes and peered through the screen's gap, and she saw her father's broad, expansive back, a narrow sweat stain tracing along his spine. Of the stranger she saw nothing but a pale, slender arm, hanging motionless off the side of the plastic chair, and a foot covered in a dirty old sneaker.
Her father straightened up and took a step back. He put his hands on his hips. He said something, too soft for Cat to discern over the sounds of cicadas whining in the trees and the ceiling fan clicking rhythmically inches from her father's head. He sighed. Then he walked across the porch to the wicker table in the corner and set down a thin metal tool that gleamed in the porch's yellow light.
There was a person sitting in the plastic chair, only he didn't seem like a person at all. His eyes focused on Cat, and she yelped and ducked into the crawl space beneath the stairs.
"Do we have a visitor?" said Cat's father, his voice booming out into the night. Cat huddled in the cool, moist dirt beneath the house, her jar pressed between her chest and her knees. It smelled of cut grass and old rainwater. The screen door slammed. Footsteps rattled Cat's hiding place. Then her father's face appeared, white and round as the moon. "What have you got there, Kitty-Cat?" He pointed at her jar of fireflies.
"It's my light-jar."
"I see," said her father. "And a lovely light-jar it is." He reached under the stairs and plucked her out, swinging her through the cool night air and bringing her to rest on his hip. "I have someone I want you to meet."
Cat buried her face in his soft shoulder.
He carried her into the screened-in porch. The light inside was weak and old-looking and buzzed like the cicadas outside. The man sitting in the plastic chair looked at Cat's father, then at Cat. His eyes moved before his head did. They were very dark, like two holes set into his face.
"Cat, this is Finn. He's come to stay with us."
Cat didn't say anything, just pulled the firefly jar to her chest and wiggled out of her father's grasp so she slid down the side of his leg. Finn nodded and then smiled at her.
"A child?" he said. Cat wanted to run back out into the darkness.
"Yes, Finn," said Cat's father. "That's right. My child. My daughter." His enormous hand ruffled Cat's hair. He knelt down beside her, and she looked at him. "Why don't you show Finn your light-jar?"
Cat didn't want to show Finn anything. He unnerved her. In certain ways Finn resembled the few adults Cat had seen in her short life his height, his long torso and limbs, the solidity of the features of his face but otherwise he was completely different from the boisterous scientists who came over some evenings for dinner parties. His eyes loomed steadily in the buzzing light of the porch. His skin was much too fair, sallow beneath the swath of black hair that flopped across his forehead.
She decided he must be a ghost. He was an adult who died. Her father brought him here to study him. This was the only logical explanation.
Cat hugged the jar tight against her chest. Finn didn't move, didn't even twitch the muscles in his face.
"Don't be rude," her father said gently. "We need to welcome Finn into our home." He straightened up, and Cat took a deep, shaking breath and stepped forward, feet rasping across the porch's painted wooden floor. She held the firefly jar out at arm's length and looked over her shoulder at the porch screen dark with nighttime. When the weight of the jar lifted out of her hands, she scurried back behind her father.
"Photuris pennsylvanicus," said Finn. "The woods firefly. "
Cat's father laughed. "Latin names," he said. "Good to know that scholarly upgrade is working nicely."
Finn held the jar up to eye level but in the light, Cat noticed, the fireflies looked like ugly brown beetles.
Cat tugged on her father's sleeve. "It's only outside," she whispered when he glanced down at her. "It's only a lightjar outside." She wondered what would happen if Finn stepped beyond the boundaries of the porch, if the yellow light made him visible, if his true nature would cause him to melt back into the shadows.
Finn ignored them, turning the jar over in his hands, gazing at it with his peculiar, dispassionate expression.
"Oh, of course!" said her father. "Finn" Finn's head jerked up. "Let's go outside. Come along."
Finn stood, his narrow body unhinging at the waist. He handed the jar to Cat and smiled, but Cat grabbed the jar and pushed through the door, out into the cool, dampening night. The fireflies glowed again. She could hear them knocking against the glass.
"How lovely," said Cat's father.
"Lovely," repeated Finn, as though the meaning of the word eluded him.
For a moment Cat stood in the darkness, her back to Finn and her father. She wasn't ready yet to see what Finn had become in the darkness. The surrounding forest rustled and shimmered against the starry sky. The glass from the jar was warm beneath her hands. She wondered if fireflies could protect you from ghosts. Probably not if they were trapped in a jar. Cat bit down on her lower lip, and then she unscrewed the lid and the fireflies streamed out, leaving streaks of light in their wake. Cat dropped the jar to her side. She took a deep breath. She turned around and gasped.
Finn had blended into the darkness, just as she predicted, but his eyes, gazing levelly out at the forest, shone as silver as starlight.
That night, Cat couldn't sleep. Whenever she closed her eyes, she saw two flat discs of silver, and her heart pounded violently up near her throat. She pulled her reading tablet out of its drawer and turned it on. She tapped the little ghost icon to bring up all the ghost stories contained in the database of the house's main computer, and she began to read, looking for clues as to how to protect herself from Finn.
