I was going to be late for school if I didn’t leave soon, but I couldn’t move from my spot. The alien invasion had begun. I watched through my phone’s screen as UFOs drifted down from the blue morning sky onto my front yard below.

I banged my finger against the screen, firing lasers at every enemy spaceship until they were all gone, and the words YOU SAVED THE EARTH flashed on the screen. Smiling broadly, I looked up to high-five my best friend, Charlie Tepper, but he wasn’t there.

“Hey, Bex, did you win?” he called from his front yard next door.

At some point, he’d stopped playing and had wandered over to toss a football with his older brother, Jason. That was a sight I’d never get used to. Until recently, Jason’s only contact with his brother was to bully and insult him. But after we nearly lost Charlie in an, um, monster incident, Jason had been nicer. And it helped that, once he actually began spending quality time with Charlie, Jason realized that his nerdy little brother had a secret. Surprisingly, Charlie had quite an arm on him. So Jason had made it his life’s mission to teach Charlie everything he could about football. I didn’t think Charlie would be interested for longer than a day. But it had lasted the rest of the summer, and he’d even joined the middle school football team. Though I still clung to the hope that the whole thing would be a passing fad.

“Of course I won,” I said as I strolled over to them.

It wasn’t as conceited as it sounded. I’d be the first to admit the things I was bad at (which were many). But gaming wasn’t one of them. I was an awesome gamer, and I’d even started to teach myself how to code using online apps. It came easy to me, like science did to Charlie. Though he spent less time doing chemistry experiments in his basement these days.

“Heads up!” Jason yelled.

I ducked just in time to avoid getting a football lodged in my nostril.

“We should go,” Charlie said. “See you later, Jason.”

Jason was a freshman and thankfully the high school was in the opposite direction. I liked walking to middle school with Charlie alone. Lately it seemed like the only time we got to really talk. We only shared one class together—science. And lunch was so crowded that sometimes in all of the chaos, we didn’t end up at the same table.

Things had been so much simpler in elementary school.

“So what did you think of that science homework?” I asked, hefting my backpack higher on my shoulder.

“It was pretty easy.” Charlie kicked at a pebble and it flew a few feet in front of us. “The field trip tomorrow night sounds awesome.”

“Yeah, it does.” I kicked the pebble farther. This was a game we played most mornings. We’d find a pebble and take turns kicking it all the way to school.

He took a turn, launching the pebble ten feet down the sidewalk. “You’re really into Alien Invasion, huh? Do you think it’s as good as Monsters Unleashed?”

The makers of Alien Invasion, Veratrum Games, had previously created a game called Monsters Unleashed. We’d been totally obsessed with it over the summer. Until some of the video game monsters got really unleashed and we had to save the town from real live snarling beasts.

“It’s not quite as good, but it feels safer.” I laughed, and he joined in.

Both of us had vowed never to play Monsters Unleashed again. But I was happy when Alien Invasion came out. It was another augmented reality game, which meant that when you were playing, it looked like the game was taking place in the real world. It used the phone’s camera and graphics card to do the trick. And there was nothing like battling video game aliens in your school parking lot.

Even our science teacher, Mr. Durr, liked the game. If you played at night, there was a really cool extra feature that “was actually educational,” he said. When you held the phone up to the sky, a star map filled in, showing exactly what stars and planets you were looking at. I’d learned a lot about astronomy while I protected our planet from fake aliens.

“You still haven’t played at night yet,” I pointed out.

Charlie’s parents had finally agreed to get him a cell phone after he’d joined the football team, so that he could text them when it was time to pick him up from practice. When we used to play mobile games together, he always had to borrow his mother’s phone. It was great that he now had his own—if he ever had free time to use it.

“I’ve heard the game’s ten times cooler at night,” Charlie said.

My face lit up as I thought of an idea. “How about tonight? Eight p.m. My backyard. The weather app this morning said it was going to be clear skies. Perfect for playing!”

Charlie held the school’s front door open for me. “I can’t. I have football practice after school. And then I’m going out for ice cream with the team. And then I’ll have to do all my homework.”

My heart sank into my gray Converse sneakers. I followed him into the school, feeling like I was losing my best friend. We’d been inseparable since I’d moved in next door when we were five. We didn’t even mind when other kids teased us about being boy/girl best friends. But since we started middle school three weeks ago, things felt like they were changing. Or, more specifically, Charlie was changing.

“Hey, do you have any new science jokes?” I asked. “You haven’t told me one in a while.”

Charlie raised his eyebrows. “You hate my science jokes.”

“I don’t hate them.”

He gave me a look.

“Okay, I used to think they were a little annoying,” I admitted. “But, strangely, I miss them.”

His science jokes were totally dorky, and he sometimes came out with them at inappropriate times. But everything was suddenly moving too fast. I just wanted one thing to stay the same.

“Well, I can’t think of any right now,” he said with a shrug.

Then the bell rang so loudly it made my ears ache.

“Gotta go!” Charlie called.

Kids darted left and right, squealing with their friends. I shuffled toward my classroom, head down, feeling like a lost puppy. Then I felt a shove, like someone had pushed my backpack. I looked around, but the hall was chaos. It was probably an accident, some kid bumping me while trying to squeeze by.

I settled into my seat in English class and put my backpack on the floor. But then I noticed something. A white piece of paper had been shoved into the side pocket. I glanced around. No one was paying any attention to me, as usual. So I slipped the note out and unfolded it. When I saw what it said, my heart did a cartwheel.

YOU’RE INVITED
TO JOIN TGS. TONIGHT,
THE COMMON, 7 P.M.

What was this? A secret group? I had no idea.

But I couldn’t wait to find out.
