When a global sonic weapon turns sound into a death sentence, the Earth’s loudest heroes are brought to their knees. Overnight, the world goes deafeningly mad—except for Astra. Born deaf and non-verbal, Thor’s daughter is completely immune to the psychic scream crippling the Avengers. As her teammates fall to the chaos, Astra boots up her silent suit, charges her zero-decibel lightning, and steps onto the front lines alone. The universe is about to learn that the quietest Avenger hits the hardest—and she doesn't need a single word to save the world.
