Josie paused the DVD. There was Courtney, and Haley, and Maddie, and John, and Drew. She touched her finger to each of their foreheads, getting a tiny electric shock each time.

At her birthday party, they’d had a barbecue at Storrs Pond. There were hot dogs and hamburgers and sweet corn. They had forgotten the ketchup and someone had to drive back into town to buy some at a mini-mart. Courtney’s card had been signed BFF, best friends forever, even though Josie knew she’d written the same thing on Maddie’s card a month earlier.

By the time the screen fuzzed out again and her own face came on, Josie was crying. She knew what was coming; she remembered this part. The camera panned back and there was Matt, his arms around her as she sat on his lap on the sand. He had taken off his shirt, and Josie remembered that his skin had been warm where it pressed up against hers.

How could you be so alive one moment, and then have everything stop-not just your heart and your lungs, but the way you smiled slowly, the left side of your mouth curling before the right; and the pitch of your voice; and the habit you had of tugging at your hair when you were doing your math homework?

I can’t live without you, Matt used to say, and now Josie realized he wouldn’t have to.

She couldn’t stop sobbing, so Josie pushed her fist into her mouth to keep herself from making noise. She watched Matt on the screen the way you might study an animal you had never seen before, if you had to memorize it and tell the world later what you’d found. Matt’s hand splayed across her bare stomach, grazed the edge of her bikini top. She watched herself push him away, blush. “Not here,” her voice said, a funny voice, a voice that didn’t sound like Josie to her own ears. You never did, when you heard yourself on tape.

“Then let’s go somewhere else,” Matt said.

Josie ruched up the edge of her pajama top, until she could reach underneath. She spread her own hand across her belly. She edged her thumb up, like Matt had, to the curve of her breast. She tried to pretend it was him.

He had given her a gold locket for that birthday, one she hadn’t taken off since that day nearly six months ago. Josie was wearing it on the DVD. She remembered that when she’d looked at it in the mirror, Matt’s thumbprint had been on the back, left behind after he clasped it around her neck. That had seemed so intimate, and for a few days, she had done everything she could to keep it from rubbing off.

On the night that Josie had met Matt out in her own backyard, beneath the moon, he’d laughed at her pajamas, printed all over with pictures of Nancy Drew. What were you doing when I texted you? he asked.

Sleeping. Why did you have to see me in the middle of the night?

To make sure you were dreaming about me, he said.

On the DVD, someone called out Matt’s name. He turned, grinning. His teeth were wolf’s teeth, Josie thought. Sharp, impossibly white. He stamped a kiss on Josie’s mouth. “Be right back,” he said.

Be right back.

She pressed Pause again, just as Matt stood up. Then she reached around her neck and ripped the locket off its thin gold chain. She unzipped one of the couch cushions and pushed the necklace deep inside the stuffing.

She turned off the television. She pretended that Matt would be suspended like that forever, inches away from Josie so that she could still reach out and grab him, even though she knew that the DVD would reset itself even before she left the room.

Lacy had known they were out of milk; that morning, as she and Lewis sat like zombies at the kitchen table, she had brought it up:

I hear it’s going to rain again.

We’re out of milk.

Have you heard from Peter’s lawyer?

It devastated Lacy to know that she could not visit Peter again for another week-jail rules. It killed her to know Lewis hadn’t been there to see him at all yet. How was she supposed to go through the motions of an ordinary day, knowing that her son was sitting in a cell less than twenty miles away?

There was a point where the events of your life became a tsunami; Lacy knew, because she’d been washed away once before by grief. When that happened, you would find yourself days later on unfamiliar ground, rootless. The only other choice you had was to move to higher ground while you still could.

Which is why Lacy found herself at a gas station buying a carton of milk, although all gut instinct told her to crawl under the covers and sleep. This was not as easy as it seemed: to get the milk, she had to first back out of her garage with reporters slapping the car windows and blocking her path. She had to elude the news van that followed her to the highway. As a result, she found herself paying for the milk at a service station in Purmort, New Hampshire-one she rarely frequented.

“That’s $2.59,” the cashier said.

Lacy opened her wallet and extracted three dollar bills. Then she noticed the small, hand-lettered display at the register. Memorial Fund for the Victims of Sterling High, the sign read, and there was a coffee can to hold the donations.

She started shaking.

“I know,” the cashier sympathized. “It’s just tragic, isn’t it?”

Lacy’s heart was pounding so fiercely she was certain the clerk would hear it.

“You’ve got to wonder about the parents, don’t you? I mean, how could they not have known?”

Lacy nodded, afraid that even the sound of her voice would ruin her anonymity. It was almost too easy to agree: Had there ever been a more awful child? A worse mother?

It was simple to say that behind every terrible child stood a terrible parent, but what about the ones who had done the best they could? What about the ones, like Lacy, who had loved unconditionally, protected ferociously, cherished mightily-and still had raised a murderer?

I didn’t know, Lacy wanted to say. It’s not my fault.

But she stayed silent because-truth be told-she wasn’t quite sure she believed that.

Lacy emptied the contents of her wallet into the coffee can, bills and coins. Numb, she walked out of the gas station, leaving the carton of milk on the counter.

She had nothing left inside. She’d given it all to her son. And that was the greatest heartbreak of all-no matter how spectacular we want our children to be, no matter how perfect we pretend they are, they are bound to disappoint. As it turns out, kids are more like us than we think: damaged, through and through.

Ervin Peabody, the professor of psychiatry at the college, offered to run a grief session for the entire town of Sterling at the white clapboard church in its center. There was a tiny line item in the daily paper and purple flyers posted at the coffee shop and bank, but that was enough to spread the word. By the time the meeting convened at 7:00 p.m., cars were parked as far as a half mile away; people spilled through the open doors of the church onto the street. The press, which had come en masse to cover the meeting, was turned away by a battalion of Sterling policemen.

Selena pressed the baby closer against her chest as another wave of townspeople pushed past her. “Did you know it was going to be like this?” she whispered to Jordan.

He shook his head, eyes roaming over the crowd. He recognized some of the same people who’d come to the arraignment, but also a host of other faces that were new, and that wouldn’t have been intimately connected to the high school: the elderly, the college kids, the couples with young babies. They had come because of the ripple effect, because one person’s trauma is another’s loss of innocence.

Ervin Peabody sat in the front of the room, beside the police chief and the principal of Sterling High. “Hello,” he said, standing up. “We’ve called this session tonight because we’re all still reeling. Nearly overnight, the landscape’s changed around us. We may not have all the answers, but we thought it might be beneficial for us to start to talk about what’s happened. And maybe more importantly, to listen to each other.”
