As I made my way back upstairs, the tightness in my chest vanished, lifting away with the comforter as I kicked it to the floor. The head-splitting pain released its grip on my brain, leaving me feeling like my tank had run empty. I had to close my eyes to block out the sight of my room swaying in the darkness.

And then it was morning. My alarm went off at seven exactly, switching over to the radio, just as Elton John’s “Goodbye Yellow Brick Road” was starting. I remember sitting straight up in bed, more surprised than anything. I touched my face, my chest. The room seemed unnaturally bright for so early in the morning, despite the curtains being closed, and within only a few minutes, the headache had crept back in, claws out.

I rolled out of bed and onto the floor, my stomach turning with me. I waited until the dark spots had stopped floating in my eyes, and tried to swallow to ease my dry throat. I knew this feeling—I knew what the clenching in my guts meant. Sick. I was sick on my birthday.

I stumbled out of bed, changing into my Batman pj’s on the way to the door. Mom would be even angrier at me if she knew I had slept in my nice button-down shirt; it was wrinkled and drenched in sweat, despite the cold clinging to my bedroom window. Maybe she’d feel bad about the night before and let me stay home to show how sorry she was.

I wasn’t even halfway down the stairs when I saw the wreckage in the living room. From the landing, it looked like a pack of animals had gotten in and had a field day throwing around pillows, overturning an armchair, and smashing every single glass candleholder that had been on the now-cracked coffee table. Every picture on the fireplace mantel was facedown on the ground, as were the line of school portraits my mom had placed on the table behind the couch. And then there were the books. Dozens of them. Mom must have emptied out every book in the library in her anger. They littered the ground like rainbow candy.

But as scary as that room was, I didn’t feel like throwing up until I reached the last step and smelled bacon, not pancakes.

We didn’t have many traditions as a family, but chocolate pancakes on birthdays was one of them, and the one we were least likely to forget. For the past three years they’d forgotten to leave out milk and cookies for Santa, somehow forgotten their pact that we would go camping every Fourth of July weekend, and even, on occasion, forgot to celebrate St. Patrick’s Day. But forgetting the birthday pancakes?

Or maybe she was just mad enough at me not to make them. Maybe she hated me after what I had said last night.

Mom had her back to me when I walked into the kitchen and shielded my eyes from the sunlight streaming through the window above the sink. Her dark hair was pulled back into a low, messy bun, resting against the collar of her red robe. I had a matching one; dad had bought them for Christmas the month before. “Ruby red for my Ruby,” he had said.

She was humming under her breath, one hand flipping the bacon on the stove, the other holding a folded newspaper. Whatever song was stuck in her head was upbeat, chipper, and, for a moment, I really did think the stars had aligned for me. She was over last night. She was going to let me stay home. After months of being angry and upset over the tiniest things, she was finally happy again.

“Mom?” Then again, louder. “Mom?”

She turned around so quickly, she knocked the pan off the stove and nearly dropped the gray paper into the open flame there. I saw her reach back and slap her hand against the knobs, twisting a dial until the smell of gas disappeared.

“I don’t feel good. Can I stay home today?”

No response, not even a blink. Her jaw was working, grinding, but it took me walking over to the table and sitting down for her to find her voice. “How—how did you get in here?”

“I have a bad headache and my stomach hurts,” I told her, putting my elbows up on the table. I knew she hated when I whined, but I didn’t think she hated it enough to come over and grab me by the arm again.

“I asked you how you got in here, young lady. What’s your name?” Her voice sounded strange. “Where do you live?”

Her grip on my skin only tightened the longer I waited to answer. It had to have been a joke, right? Was she sick, too? Sometimes cold medicine did funny things to her.

Funny things, though. Not scary things.

“Can you tell me your name?” she repeated.

“Ouch!” I yelped, trying to pull my arm away. “Mom, what’s wrong?”

She yanked me up from the table, forcing me onto my feet. “Where are your parents? How did you get in this house?”

Something tightened in my chest to the point of snapping.

“Mom, Mommy, why—”

“Stop it,” she hissed, “stop calling me that!”

“What are you—?” I think I must have tried to say something else, but she dragged me over to the door that led out into the garage. My feet slid against the wood, skin burning. “Wh-what’s wrong with you?” I cried. I tried twisting out of her grasp, but she wouldn’t even look at me. Not until we were at the door to the garage and she pushed my back up against it.

“We can do this the easy way or the hard way. I know you’re confused, but I promise that I’m not your mother. I don’t know how you got into this house, and, frankly, I’m not sure I want to know—”

“I live here!” I told her. “I live here! I’m Ruby!”

When she looked at me again, I saw none of the things that made Mom my mother. The lines that formed around her eyes when she smiled were smoothed out, and her jaw was clenched around whatever she wanted to say next. When she looked at me, she didn’t see me. I wasn’t invisible, but I wasn’t Ruby.

“Mom.” I started to cry. “I’m sorry, I didn’t mean to be bad. I’m so sorry, I’m so sorry! Please, I promise I’ll be good—I’ll go to school today and won’t be sick, and I’ll pick up my room. I’m sorry. Please remember. Please!”

She put one hand on my shoulder and the other on the door handle. “My husband is a police officer. He’ll be able to help you get home. Wait in here—and don’t touch anything.”

The door opened and I was pushed into a wall of freezing January air. I stumbled down onto the dirty, oil-stained concrete, just managing to catch myself before I slammed into the side of her car. I heard the door shut behind me, and the lock click into place; heard her call Dad’s name as clearly as I heard the birds in the bushes outside the dark garage.
