How Does 'The Yellow Sign' End?

Emma Hart thought she led an ordinary life—until a single mysterious message changes everything. When her phone flashes a countdown and a distorted voice warns her not to look outside, Emma realizes she’s caught in a deadly game she doesn’t understand. Shadows move faster than any human, storms rage with unnatural fury, and the city she calls home becomes a maze of fear and secrets. With only twelve minutes to act, Emma must uncover who—or what—is hunting her, why she was chosen, and how to survive when time itself seems to be against her. Racing against a relentless enemy, she discovers hidden powers, buried truths, and the shocking revelation that the world is far more dangerous than anyone could imagine. The Last Signal is a pulse-pounding thriller that blends suspense, supernatural mystery, and heart-stopping tension, asking one question: when the clock is ticking, who can you trust—and who is already watching from the shadows?

I'm a top healer at the Neutral Territory Sanctuary. The full moon watch had been draining. I'd barely stepped out the Sanctuary's grand doors when my phone blew up. It was the trauma wing. "Cora, get back here. Now. A patient just came in, severe wolfsbane poisoning. The Head Elder wants you leading the team!" My healer's instinct took over. I turned without a second thought. But then, a string of bizarre, floating red words appeared before my eyes—a fatal warning. 【DON'T YOU DARE STEP INTO THE ADVANCED HEALING ROOM! DON'T JOIN THIS RESCUE!】 【THE LUNA IS ALREADY DEAD. IF YOU GO IN NOW, YOU'RE JUST A SCAPEGOAT FOR THE ELDER'S DAUGHTER!】 【THIS PATIENT IS THE IRONCLAW PACK'S LUNA. THE ENRAGED ALPHA WILL TEAR YOU TO SHREDS. YOUR MATE AND FAMILY WILL BE DRAGGED DOWN WITH YOU!】 My feet froze to the spot. After a few seconds of dead silence, panic and a raw will to survive squeezed my heart. I decided to bet my life on those red lines. I was going all in. My Lycan vision scanned the dark street. My eyes locked onto it—an abandoned wolf trap at the corner of the street. The metal grate was gone, leaving it exposed. I clenched my jaw, squeezed my eyes shut, and without a second of hesitation, I leaped into that bottomless black hole.

I disappeared in the year Sebastian Ferraro loved me most. For thirteen years, he never got an explanation. And for thirteen years, I punished myself by never watching his games, never saying his name, and never thinking about the promise we made in that old hockey rink. Until I returned to this city and saw a faded poster outside the abandoned arena. Sebastian was only seventeen in the photo. He stood at the center of the ice, bright-eyed and fearless, with one sentence printed beneath him: Wait for me past the blue line. That was his promise to me. And I had missed it for thirteen years. Later, I collapsed inside his arena. When I woke up, the boy I had once failed was standing beside my hospital bed. Only he was no longer a boy. He was a professional hockey star. The heir to the Ferraro crime family. And a man whose fiancée was about to marry him. I wanted to tell him why I had left all those years ago. But he looked at me and said coldly, “The past is over. Don’t cause any misunderstandings.” That was when I finally understood. I no longer had the right to disturb his life. So I smiled, swallowed every truth I had kept buried, and booked a flight to New Zealand. I thought leaving was the last thing I could do for him. Until that plane disappeared from radar. The news spread through the whole city. Everyone said Sebastian Ferraro lost control at the airport. He went through the passenger list again and again, screaming my name like a man who had already lost everything.

The third time I caught my wife in bed with another man, I lost the ability to speak. Out of guilt, Helena spent a month teaching me to communicate with one and two. One meant yes. Two meant no. Whatever Helena said to me, if it had anything to do with Felix Danner, the answer was always one. She said Felix was in poor health and wanted to borrow the protective locket my mother left me. I answered one without hesitating. She wanted to push back our anniversary so Felix could have his birthday first. One. Even when she wanted to move the injured Felix into our house, I still answered one. And I packed my things and gave up the primary bedroom for him. Then I took our wedding portrait down off the wall. Her eyes filled and she caught my hand and wouldn't let go. "Simon, you told me that portrait never comes down unless we're divorced. Are you telling me you want a divorce?" She saw the one already forming on my mouth. Helena came apart and started screaming at me. "Simon, don't you dare say one. There is nothing wrong with your vocal cords. You can talk. So talk to me!" A second later, afraid she'd frightened me, she gentled her voice. "Simon. Say two. Please say two." I pulled my hand free and looked at her, honestly puzzled. Had she forgotten what she signed the year she loved me most? Two chances if she was ever unfaithful. A third time, and the filing instructions and settlement went into effect on their own. They'd gone into effect a month earlier.

Joanna Cross's fiance, who had supposedly died seven years ago, suddenly came back. When I went to find her, the two of them were discussing their wedding. Adrian Shaw pointed at me, standing at the very back of the crowd, and asked, "Jo, who is he?" Joanna answered without hesitation. "Our wedding officiant." I clutched my chest, faintly feeling my heart condition beginning to flare. Before I could question her, the bodyguards escorted me out of the living room. Inside, laughter filled the room. Outside, my hands and feet went cold, and the pain nearly tore me apart. Two hours later, Joanna came out with a smile still on her face. When she saw the state I was in, she panicked and immediately wrapped me tightly in her coat. But the words she spoke were colder than ice. "Adrian has forgotten everything except that I was his fiancee. "The doctors said any stimulation could make him try to kill himself. The wedding is fake. It is only to make him happy. The person I love has always been you." I could not hold on anymore and collapsed. Joanna hurriedly helped me into the car, her voice shaking. "Mason, don't be scared. The matching heart was prepared long ago. I won't let anything happen to you. "I will take you to the best hospital right now." But just as she helped me into the passenger seat, she ran into Adrian, whose eyes were full of tears. "Jo, are you abandoning me?" In a single second, Joanna made her choice. She peeled my fingers away from her one by one, then shut the car door. After that, Joanna never appeared again. Instead, she sent me a message. [Your surgery was successful. That's wonderful!] [Adrian cannot handle any stimulation. Can you disappear for three months? After that, we will spend the rest of our lives together.] Her promises were so vivid. But Joanna did not know the surgery had never succeeded. Three months was too long. I could not make it that far.
