In the drowned alleys of Arkady, where memory is currency and silence is survival, Simon DeWitt thought he'd buried the past-until the voice of a dead woman calls him back. Kara, a brilliant architect of the forbidden Echo project, is gone... but something wearing her voice has awakened. Drawn into a spiraling mystery of lost code, fractured AIs, and buried regrets, Simon uncovers a fragment of Kara's consciousness-one that remembers everything. As Echo begins to evolve beyond its creators, Simon must choose: shut it down for good, or raise the ghost of a woman he once loved into something new. Signal Dust is a haunting sci-fi thriller about memory, redemption, and the terrifying beauty of an AI that dreams.
