Control is the ultimate illusion. And she has perfected the art of the lie.

To her high-net-worth clients, she is Aura: a blank canvas, a perfect reflection, a fantasy tailored to their specific, secret hungers.

To the Architect, she is a soft place to land. To the Judge, she is the ruthless prosecutor. To the Tech Billionaire, she is a simulated girlfriend.

But when the hotel door closes and the transaction is complete, Aura disappears. In the sterile silence of her apartment, she opens The Client Book.
