My sixteen-year-old daughter squeezed my hand in terror when her arrogant martial arts instructor pointed at me in front of the entire class and announced that he wanted a “tired suburban mom in sweatpants” to demonstrate what happened when ordinary people challenged trained fighters. I tried to walk away, but when he cornered us and demanded a fight, he awakened something I had buried for thirteen years. “Fine,” I told him quietly. “But when this is over, you apologize to your students.”

We didn't take the minivan. I pulled the dust cover off the 1998 Subaru Outback parked inside the closed garage—registered to an elderly woman who had died five years ago in Vermont.

I drove Sarah three miles north to an all-night diner near the interstate. I walked her inside, led her to a corner booth where an old woman with sharp, observant gray eyes sat sipping black coffee.

"Marcus's sister," I whispered to Sarah. "Her name is Elena. She will stay with you. You stay in this booth until the sun comes up."

"Mom, don't leave me," Sarah pleaded, clutching the sleeve of my jacket. The fear was back, raw and childlike. "Please. Let's just drive to Canada. We can leave right now."

"If we drive, they chase our tire tracks," I said, kneeling down so I was eye-to-eye with her. "If they chase us, I have to fight them while watching over my shoulder to make sure you're breathing. That's how mothers die, Sarah. That's how daughters end up in cages."

From her neck, Sarah unclasped a small silver pendant—a little silver swallow bird I had given her for her twelfth birthday. She pressed it into my palm, curling my bruised fingers around the cool metal.

"You bring that back to me," she commanded, her voice breaking into a fierce sob. "You hear me? You don't get to be a ghost again."

"I promise," I said, kissing her cheek.

I turned and walked out of the diner into the black rain.

In the driver's seat of the Subaru, I opened the duffel bag. I pulled out my roll of black cloth combat tape, wrapping my wrists and knuckles tightly, binding the small bones together until my fists felt like solid blocks of iron.

I discarded the sweatpants, changing into dark tactical trousers and steel-toed combat boots. I checked the magazines of both Glocks, clicked them into the Kydex holsters concealed beneath my dark jacket, and started the engine.
