The Perception Index (Paperback) (ISBN-13: 9798253965740)

The sky hasn't changed. You have.

Dr. Mara Ives helped build the Perception Index - a global system promising calm, stability, and an end to the anxiety that was quietly destroying the world. It worked. Beautifully. Until she arrived in a city that didn't finish updating, and found children drawing things adults could no longer see.

Now the system she designed is watching her. And what it's hiding is older, vaster, and more patient than anything she was trained to measure.

The truth was never the danger. Looking was.
