Chapter 154
Chapter 154:
The front door opened. The nanny, a kind older woman named Mrs. Gable, ushered Effie inside.
“Mommy!” Effie ran in, dropping her backpack — then stopped dead when she saw the cast.
Her large eyes filled with tears. “Mommy? You’re broken p>
Isolde forced a smile. “Just a little crack, baby. Like a teacup. It’ll fix p>
Effie walked over slowly and touched the white plaster with a single finger. “Does it hurt p>
“Not when I look at you,” Isolde said. “How was school p>
Effie nodded vaguely. Then she did something unexpected — instead of climbing onto the sofa for a cuddle, she grabbed her backpack and bolted for her bedroom.
“Effie?” Isolde called.

The bedroom door clicked shut.
Isolde frowned. She struggled to her feet, the room tilting slightly, and walked to Effie’s door and pushed it open.
Effie was lying on her stomach on the rug. In front of her was Isolde’s old engineering tablet — the backup that hadn’t been destroyed — its screen glowing blue.
“Effie p>
Effie startled. She tried to slide the tablet under her chest. “Sorry! Sorry, Mommy! I didn’t mean to touch p>
“It’s okay,” Isolde said, kneeling carefully and wincing as her arm jarred. “Let me see p>
Effie handed it over with trembling hands.
Isolde looked at the screen. It was open to a draft file she had been working on late the previous night — a trajectory calculation for a low-orbit satellite. She had been stuck on a single variable for hours. A small, highlighted annotation had been added to the screen, pointing to a specific section of a long string of code.
Isolde stared. Her heart began to hammer against her ribs.
“Effie,” she whispered. “Did you do this p>
Effie looked down at her knees. “The number was wrong, Mommy p>
“How did you know it was wrong p>
“It sounded scratchy,” Effie said, rubbing her ear. “Like when a violin string snaps. The song in the math was broken p>
Isolde looked at her daughter. Synesthesia. Number-form synesthesia — the ability to perceive numerical relationships as sensory inputs: sound, color, texture. It was rare. In engineering, it was a superpower.
She looked back at the screen, her eyes tracing the line Effie had marked. The girl was right. It was a subtle, almost imperceptible flaw — a non-linear distortion that would only manifest under extreme G-force, triggering a catastrophic feedback loop. The computer hadn’t caught it.
But Effie had heard it.
“You found it,” Isolde breathed. “Effie, you found the flaw p>
Effie looked up, hopeful. “I fixed it p>
“You helped Mommy fix it p>
Isolde pulled Effie into a one-armed hug and buried her face in her daughter’s hair. Tears came fast and hot, soaking into Effie’s shirt. For five years, Grayson had called Effie slow. He had called her spacey. He had dismissed her because she hadn’t spoken in full sentences until she was four.
But she wasn’t slow. She was operating on a frequency he couldn’t even hear.
“You are a genius, Effie,” Isolde choked out. “You are Mommy’s brilliant girl p>
Effie smiled — a true, blinding smile.
