Chapter 1

The voice came from the mirror. Nathan's own reflection stared back, but beside it—no, inside it—stood a man he had never seen before. The man had Nathan's eyes, the same shade of gray-blue, but his face was older, maybe forty, with lines around his mouth and a thin white scar that cut across his lower lip. He wore a faded flannel shirt that looked like it had been washed a thousand times.

Nathan's hand tightened on the edge of his desk. He had been studying for tomorrow's history exam when a flicker in the glass caught his attention. Now his bedroom felt too small, the walls too close.

"Who are you?" Nathan managed. His voice came out steadier than he expected.

The man smiled, and the scar pulled tight. "I'm you. Twenty-five years from now."

Nathan shook his head. "That's not possible."

"Is it?" The man raised his hand, and Nathan saw his own arm lift in the mirror at the exact same moment—except the man's hand stopped at chest height, while Nathan's kept going. They weren't synchronized. They weren't the same reflection.

"Check your backpack," the man said. "The inside pocket. You lost your phone this morning."

Nathan had spent fifteen minutes before school tearing apart his room looking for it. He unzipped his backpack now, fingers fumbling. There, in the small pocket he rarely used, his phone rested against a crumpled bus pass. He pulled it out, the screen glowing.

"How did you know?"

"I remember losing it. You put it there by accident after grabbing your calculator. It happens to everyone." The man's voice was calm, almost gentle. "I can help you with more than lost phones, Nathan. I know what's coming."

Nathan sat on the edge of his bed, the phone still in his hand. The room felt different now, as if the air had thickened. He had always been a lonely kid—not bullied, just invisible. His parents loved him, but they worked long hours, and his only real friend, Owen, had been busy lately with his own life. Nathan spent most evenings in this room, doing homework or scrolling through his phone. The idea that someone, even a reflection, wanted to talk to him felt like a door opening.

"What's coming?" Nathan asked.

The man's expression turned serious. "Tomorrow morning, you'll ride your bike to school like always. But on Maple Street, a car will run a red light. You'll swerve, hit the curb, and break your wrist. It'll heal, but you'll miss the summer soccer tryouts."

Nathan's stomach tightened. Soccer was the one thing he was good at. "How do you know that?"

"Because it happened to me. To us. And I don't want it to happen again."

The man pressed his palm against the glass, and Nathan saw his own reflection doing the same. For a moment, they looked like two people reaching for each other across a divide.

"Stay home tomorrow," the man said. "Tell your mom you feel sick. It's a small change, but it'll save your wrist."

Nathan didn't sleep well that night. He kept glancing at the mirror, but the man was gone, replaced by his own tired face. In the morning, he pretended to have a stomachache. His mother felt his forehead, frowned, and let him stay home.

At 8:15, he heard sirens on Maple Street.

That afternoon, he stood in front of the mirror again, his heart pounding. "It worked. The accident—I heard it."

The man was back, sitting on a chair in the reflection that didn't exist in Nathan's room. The chair looked old, upholstered in worn brown fabric. "I told you. I'm trying to help you."

"Why?" Nathan asked. "What do you get out of this?"

The man leaned forward. "I get to fix my mistakes. Every time you avoid one, it makes my life better too. It's... complicated. But trust me, Nathan. This is for the best."

Nathan wanted to believe him. The proof was there—the phone, the accident. And the man knew things, private things, like the time Nathan cried in third grade because his dog died, or the joke he and Owen shared that no one else understood.

"There's more I can show you," the man said. "But first, I need you to do something for me. Something small."

Nathan felt a flicker of unease, but it was drowned by curiosity. "What is it?"

"In your mother's desk, there's an old letter. I need you to hide it where she won't find it. Just for a day."

Nathan's hand went to his pocket, where his phone buzzed with a text from Owen. He ignored it. His eyes stayed on the man in the mirror, whose scar seemed less prominent now, as if the wound was healing.

"Why?" Nathan asked again.

"Because it'll make things better. For both of us." The man smiled, and Nathan saw something in his eyes—relief, maybe, or hunger. "Will you help me, Nathan?"
