In the silence after the world ends, one voice begins to rise. Hazel wakes in a bunker with no memory-only the feeling that someone she loved was taken from her. Outside, the world has been lost to the Changed-once-human horrors twisted by a lab-born virus that was hidden in something meant to save them. Inside, the survivors cling to routine, secrets, and the fragile hope that the past can stay buried. But Hazel isn't just another refugee. As she pieces together the fragments of her life, her presence stirs something in the people around her. A bond forms with Devon, the guarded sentry who has more to lose than he admits. A fire reignites in Dani, whose long-lost brother may be closer than she dares to hope. And the children in the bunker-those too young to remember a world before-begin to believe again. When Hazel's voice unites fractured survivor groups, the balance begins to shift. Together, they strike back against the Red Bands, a brutal regime led by the cold and calculating Marrow. Capturing her is just the beginning. Holding onto hope, leadership, and each other may prove harder. Because survival isn't enough anymore. They want something worth fighting for.
