My sister ruined my glasses the morning of my thesis defense. She laughed and expected me to fail. I had other plans.

Lila had never cared about my work until she learned that a medical technology company might license it.

Then she started asking strange questions.

How much could it be worth?

Who owned the patent?

Would I “share with family”?

Two weeks earlier, I had walked into my room and found one of my desk drawers open.

So I stopped leaving anything important there.

I picked up the tape but didn’t use it.

Lila laughed. “What? Too proud?”

“No,” I said. “Just thinking.”

She mistook calm for defeat.

They all did.

Dad stood. “You should call the department and apologize. Maybe they’ll let you reschedule next semester.”

“Next semester?” Lila said, delighted. “That’s generous.”

My phone had disappeared from the charging stand beside the refrigerator.

I looked at Lila.

She smiled wider.

That was when I knew this wasn’t just cruelty.

It was coordinated.

They needed me to miss the defense.

What they didn’t know was that Professor Shaw and I had prepared for exactly one possibility: interference.
