She erased her grief. Now it has a body—and it remembers everything.
In a world where grief is illegal, Dr. Mara Lior makes a fatal mistake: she tries to cut her daughter out of her mind.
The procedure was supposed to erase four years of mourning. Instead, it rips those memories free as Echo—a separate consciousness with Mara's grief, her rage, and her daughter's face.
Now Mara is a prisoner, forced to hunt the anomaly she created. Echo is a fugitive who becomes the resistance's most dangerous weapon. Two halves of one shattered soul, on opposite sides of a war neither wanted.
But their enemies have discovered something terrifying: the only way to destroy Echo is to reclaim her. And the only way to save Echo is to let Mara die.
