The world didn't end in fire or ice—it ended in silence. First, the satellites went dark. Then the skies turned black with ash. Three days later, the sky cracked open . Now, a decade after the Event, what remains of humanity clings to survival beneath the ruins of dead cities and poisoned skies. In the wasteland, survival means silence—because something is still listening. Seventeen-year-old Kael Renn , raised in an underground enclave, has only known the rules of survival: stay quiet, trust no one, and never go topside after dusk. But when a distress signal pulses through a forgotten relay tower, Kael breaks protocol—and discovers a hidden outpost broadcasting one final message: "There is still time." Forced to brave a surface world crawling with ash-born predators and fractured war machines, Kael teams up with a rogue scavenger and an exiled AI to uncover the truth behind the apocalypse—and the horrifying secret buried beneath the Ashfall.
