I might not be a scientist, but you don’t need advanced degrees to realize that red equals bad.

My first impulse was to open the garage door and yell for Paul and Theo, but Theo sometimes wound up parking way down the road. So I grabbed my cell phone instead. I hit Paul’s number, and he answered, short and brusque as ever: “Yes?”

“This—thing from Triad, the one in the corner? Should it be flashing red?”

He paused for less than a second. When he spoke again, the intensity of his words gave me chills. “Get out of there. Now!”

I turned to Josie. “Run!” Instantly she fled; Josie’s smart like that. Me? Not quite. I’d kicked off my shoes and so I spent three precious seconds stepping back into them before dashing to the door. Just as I hit the threshold, though—

The light was as brief as a camera flash but a hundred times brighter. I cried out, because it hurt my eyes, and dizziness rushed over me, maybe from moving too fast. Losing my balance, I staggered onto the front steps and tried to suck in a breath, but it was hard to do, as if someone had punched me in the gut.

Then broad, strong hands closed around my shoulders, and when my vision cleared, I was looking up into Paul’s eyes.

“Marguerite? Are you all right?”

“Yeah.” I leaned forward, trying to find the angle that would allow me to steady myself. Cool rain had begun to fall, but very lightly, almost a mist. My forehead rested against his broad chest; I could feel his heart beating quickly through his damp T-shirt, as if he were the one afraid.

“What happened?” Theo came running across the yard then, his Doc Martens splashing through the mud. “Marguerite? What happened?” Josie came running up too.

“That damned Triad machine is what happened!” Paul kept holding on to me, but his fury shook me even then—hinting, maybe, at the real Paul inside. “Did you set it to run an overload test?”

“No! Are you crazy? You know I wouldn’t do that and leave it unattended.”

“Then why did it overload?” Paul demanded.

“What? It did?” Theo looked so stricken. “Jesus. How did that happen?”

“What almost happened?” Josie demanded. “Do I even want to know?”

“No, you don’t.” Paul’s fingers tightened around my shoulders; he was gripping me so hard it bruised. I can’t explain how that was intimidating and comforting at the same time, but it was. He wasn’t looking at me any longer. “Theo, who gave you this? Was it Conley himself? Someone from Triad could have preset a test without our knowing.”

Theo huffed, “Stop being so paranoid. Could you do that for once?” His voice gentled as he added, “Deep breaths, Meg. Are you all right?”

“I’m fine,” I said, and by then I was. I pulled out of Paul’s arms to stand on my own. Josie came to my side, but she was wise enough not to coddle me; she simply stayed close.

Paul walked through the mist to Theo; he’s five inches taller and a whole lot broader, but Theo didn’t flinch, even when Paul jabbed his finger against his breastbone. “Someone set up an overload test. It wasn’t you. It wasn’t me. Therefore it was Triad. That isn’t paranoia. That’s fact.”

Although Theo clearly wanted to argue, he said, “Okay, all right, maybe they made a mistake.”

“A mistake that could have hurt Marguerite! A mistake you should have caught, if you’d been paying attention. But you weren’t paying attention, were you?”

“I already admitted I screwed up—”

“It’s not enough to admit it! You have to do better than this. You have to keep yourself sharp. If you don’t—and you put Marguerite at risk again—there will be consequences.” Paul was leaning over Theo, using all his size and anger in an attempt to intimidate him. “Do you understand me?”

Theo’s entire body tensed, and for a moment I thought he might push Paul back. But that spark faded as quickly as it had begun. Quietly he said, “I hear you, little brother. I do. You know I feel like shit about this, right?”

They weren’t brothers, hadn’t even met two years before, but that nickname was something that mattered to them both. Theo, too, had taken Paul under his wing; Paul had seemed to idolize Theo, almost, more awed than envious of Theo’s easy humor and crazy social life. It’s hard to imagine that Paul didn’t mean it that day when his gaze softened and he said, “I know you’d never mean to do anything like that, Theo. But you can’t let yourself get distracted. By anything.”

“Listen, let me be the one to tell Sophia and Henry about this. I won’t hold anything back. It’s just—I deserve to hear it from them, you know?” Theo said, looking at all three of us in turn.

“Okay,” Paul said, then glanced over at me for confirmation. I nodded. Josie hesitated for a long moment, then finally nodded too. Theo inclined his head, almost as though he were bowing, and then trudged toward his car.

Paul came back to me, guiding me to the house. Apparently it was safe to be inside again. Josie followed us, pointing at the device. “Can we move that thing?”

“Good idea,” Paul said. “Get it out of the house. We probably shouldn’t have brought it in here to begin with.”

Josie hauled it into her arms—that thing was heavy—and headed out, leaving me and Paul alone.

As he pushed my hair back from my face, I felt suddenly shy. So I tried laughing it off. “What, am I radioactive now? Do I get superpowers?”
