Chapter 1

I thought our new house was haunted.
Then I opened my daughter’s bedroom wall and found a little girl breathing on the other side.
It began with small things disappearing.
Bread from the counter.
Apples from the fruit bowl.
Crackers from the pantry.
Tiny bottles of water from the garage fridge.
At first, Caroline laughed it off.
“Old houses make people paranoid,” she said.
We had moved into the house outside Boston only three weeks earlier.
It was large, old, and strange.
Too many narrow halls.
Too many locked closets.
Too many sounds in the walls at night.
I told myself every creak was wood settling.
Every whisper was wind.
Every missing item had a normal explanation.
Then I caught my four-year-old daughter, Lily, carrying two bananas and a bottle of water into her bedroom.
She froze when she saw me.
Her eyes went huge.
“Lily,” I said softly. “What are you doing?”
She hugged the food against her chest.
“Nothing.”
“Sweetheart.”
Her bottom lip trembled.
I knelt in front of her.
“Who are you feeding?”
Lily looked over her shoulder.
Not at her bed.
Not at her closet.
At the wall.
The old wall beside the heating vent.
My skin went cold.
Then I heard it.
A breath.
Small.
Shaky.
Human.
Coming from behind the wall.
I stood slowly.
“Lily, come here.”
She shook her head.
“She’s scared.”
My heart slammed.
“She?”
Lily started crying.
“She said not to tell Mommy.”
The house seemed to tilt beneath me.
I crossed the room and crouched beside the vent.
It was old brass, painted white around the edges.
One screw was loose.
The others were scratched like someone had worked at them from inside.
I grabbed a screwdriver from Lily’s craft drawer with hands that barely worked.
“Daddy?” Lily whispered.
“It’s okay.”
But I did not know that.
I removed the screws.
The vent came free.
For one second, there was only darkness.
Then two eyes stared back at me.
A little girl.
Thin.
Dirty.
Maybe five.
Her hair hung tangled around her face.
She pressed herself into the narrow space like she expected me to hurt her.
I could not breathe.
“Hi,” I whispered. “I’m Ryan.”
Her lips trembled.
“I know.”
Lily sobbed behind me.
“She was hungry.”
I reached one hand through the opening.
“I won’t hurt you.”
The girl stared at my hand.
Then at my face.
Then she crawled toward me.
Her knees scraped over the wood inside the wall.
She slid through the opening into Lily’s bedroom and collapsed onto the rug.
I caught her before she hit the floor.
She weighed almost nothing.
My chest tightened with horror.
“Who are you?” I asked.
Her small fingers gripped my shirt.
She looked up at me with eyes I had seen before.
Not in this house.
Not recently.
Years ago.
In another life.
Then she whispered one word.
“Daddy.”
The bedroom door opened.
Caroline walked in.
She stopped dead.
Her face went white.
Not shocked.
Not confused.
Afraid.
Because she already knew.
“What is going on?” I asked.
Caroline’s eyes went to the little girl in my arms.
Then to the open vent.
Then to Lily.
“Ryan,” she said carefully. “Don’t ask her anything.”
The sentence chilled me more than the child in the wall.
“Don’t ask her anything?”
“She’s confused.”
The little girl clung tighter to me.
“She knows my name,” I said.
Caroline stepped closer.
“Give her to me.”
I stood, holding the child against my chest.
“No.”
Caroline’s voice sharpened.
“Ryan.”
The girl buried her face in my neck.
“Don’t let her take me.”
Lily screamed.
“Mommy, stop!”
Caroline froze.
I looked at my wife.
The woman I had married.
The woman I had trusted with my daughter.
“What did you do?”
Caroline shook her head too fast.
“I didn’t do anything. This house has old passages. Maybe she came from outside.”
The little girl lifted her head.
“You had a blue bike,” she whispered.
My heart stopped.
“What?”
“When you were little. You fell by the lake and got stitches here.”
She touched her own eyebrow.
I staggered back.
Nobody knew that story except my parents and one other person.
Ava.
My college girlfriend.
The woman who vanished six years ago after telling me she was pregnant.
The woman everyone said had run away.
The woman Caroline told me to stop mourning.
The child reached into the pocket of her torn sweater and pulled out a folded photograph.
She placed it in my hand.
It was me.
Younger.
Asleep on a couch.
Ava beside me, smiling at the camera.
Her hand resting on her stomach.
I had never seen that picture.
My voice broke.
“Where did you get this?”
The little girl whispered, “Mommy gave it to me.”
Caroline grabbed the doorframe.
“No.”
Lily stepped toward me, crying.
“Daddy.”
I looked at her.
She pointed at Caroline.
“Mommy brings someone here at night.”
Caroline’s face turned gray.
“Lily, stop.”
But Lily shook her head hard.
“She said the wall people had to go away.”
My blood turned to ice.
I looked back at the open vent.
The space behind it was wider than it should have been.
A hidden passage.
I lowered the little girl gently onto Lily’s bed.
“What is your name?”
“Emma.”
My knees almost gave out.
Ava had once told me if she had a daughter, she would name her Emma.
I turned to Caroline.
“Where is Ava?”
Caroline whispered, “You don’t understand.”
Lily pointed toward the vent again.
“There’s another room.”
I climbed through the opening.
The passage was narrow, dusty, and cold.
Blankets lay on the floor.
Empty water bottles.
Candy wrappers.
A child’s sock.
I crawled deeper.
My shoulder scraped wood.
Ahead, beyond the blankets, I found a second concealed door.
Metal.
Old.
Locked from the other side.
I pressed my ear to it.
Silence.
Then someone behind it knocked three times.
Slow.
Weak.
Alive.
I turned back toward Caroline.
She stood in Lily’s bedroom, shaking.
“Open it,” I said.
May you like
Tears filled her eyes.
“They weren’t supposed to still be here.”
