What if the person you trusted most was never real — and neither were you? Ava thought she escaped the fire that destroyed her past. But when she wakes with no memory and the number "47" burned into her thoughts, she begins to unravel a truth buried under layers of lies, experiments, and identities that aren't hers. Pursued by a secret division of the government and haunted by a voice in her head named Echo, Ava discovers she's not just a survivor—she's the final subject of a classified experiment to weaponize the human mind. Every memory is a code. Every emotion, a key. And every person she meets may be just another part of the program. As her reality fractures and the voices multiply, Ava must choose: destroy the system that made her… or become something greater than human. 47 is a gripping psychological sci-fi thriller blending mind-bending suspense with heart-pounding twists. For fans of Black Mirror , Orphan Black , and Dark , this novel will keep you questioning everything—right up to the final page.
