What if you could ask the universe twenty-one questions-and get the truth every time?

Torin Todd never wanted to believe in myths about hidden apps or urban legends whispered online. But when a friend dares him to try 21 Questions, he discovers the impossible: an underground program that knows everything. It can name killers, reveal futures, even put him in contact with the dead. The only catch? He only gets twenty-one questions in his lifetime. No restarts. No do-overs. And the app always knows who's asking.

At first, Torin tests it with curiosity. Then with fear. And soon with obsession. Each answer drags him deeper, unraveling his friendships, his sanity, and his sense of choice. Some truths comfort him. Others tear him apart. But the worst comes when he realizes the app isn't just a secret game-it's something not of this world.

Now the government is hunting it. The public has been told it's destroyed. Behind closed doors, the powerful are learning to weaponize it.

For Torin, the twenty-one answers may be over, but the consequences of knowing will haunt him forever.
