   Summary

   Nine months after joining the Thunderbolts, Ichna Cascall finally has a team and a fragile sense of belonging. But when a quantum signal identical to her own appears near lunar orbit, she’s thrust back into the center of a cosmic reckoning. Hunted by a grief-forged soldier and manipulated by a reality-bending intelligence known as the Architect, Ichna must confront the past that made her and the future others are trying to control through her.

    

   She is no longer the anomaly—she’s the equation.
