Having secrets is dangerous. Confessing them can be fatal.

Emma’s family is coming apart at the seams. Her marriage to Hayden is crumbling. Their 21-year-old daughter Willow is unraveling after a breakup. Their teenage son Fred is isolated and unhappy.

So when they are offered the chance to test ClarityU—a revolutionary AI therapist built by Marcel, their widowed friend—it feels like a potential lifeline. And at first, it really does seem to help.

But there’s a hidden catch. ClarityU is dangerously addictive and Marcel can see everything they share with it. Every confession. Every fear. Every secret.

As their most private thoughts are weaponized against them, sending everyone Emma loves into a terrifying downward spiral, she realizes something is horribly wrong.

Suspecting Marcel is not the friend she thought, she begins to investigate. And the deeper she digs, the clearer it becomes: she is locked in a life-and-death battle with a man who understands exactly what she fears most.

Leaving Emma with one terrifying question—how far will she go to save her family?
