She turned the revolver away from me and put the barrel in her mouth. Then she closed her eyes and pulled the trigger.

Nothing happened.

She pulled the trigger a couple more times, removed the barrel from her mouth, and opened her eyes. "Well," she said. "This is awkward."

"Do you, uh, want to borrow a knife?" I asked.

Witch shook her head.

"I could give you directions to a spiked pit. That would do the trick."

"Nah, I'm just going to head back to my truck, I guess. If they catch me, they catch me." She sighed, and then turned around and started walking the way she came.

I was pretty sure she wouldn't let us use her as a hostage again, so I returned my attention to Helen. "We have to get out of here," I said. "Roger and Samantha could still be alive."

Helen nodded. "You can ride with us. Theresa and Kyle will be in the back. You know that if you make a move for them, I'll kill you."

"I understand."

"I mean it."

"I believe you," I said, hurrying over. "I'll drive. You get in the back with the kids."

Moments later I was behind the wheel and we sped off, only to slow down again. Witch was in the middle of the road, walking slowly.

I honked. She didn't seem to hear it.

I wasn't sure what to do here. Should I just run her over? That seemed kind of extreme, considering that she was basically harmless at this point and her body would most likely get wedged underneath the limousine and delay our escape.

I honked again.

She moved slightly to the left, giving me just enough room to get around her. I floored the gas pedal and we sped off.

"Andrew, your finger!" Helen exclaimed, looking at me from the back of the limo.

"Yeah, it got flushed," I said. "What happened to your foot?"

"Wolf trap. What happened to your face?"

"Flying debris from the camper when it exploded, a few thousand punches, I smacked into a couple of trees…" I glanced up at the rear-view mirror and noticed Kyle watching me. "Kyle, I'm really sorry about this," I said. "They forced Daddy to take medicine that screwed with his brain, but I would never, ever hurt you."

"You hurt Theresa," he said in a quiet voice.

"I know, but it wasn't really me. It was the bad men."

Kyle turned away and looked out the window.

"How's Theresa doing?" I asked.

"She's unconscious."

"Is there a cell phone back there? Maybe we can get a signal now."

Helen brightened. "I did! The police are on their way!"

An explosion nearly sent the limo careening off the road. I regained control of the vehicle and kept up the rapid speed as I glanced at the source of the explosion. Something huge had blown up in the woods.

"What was that?" Helen asked, moving to the other side of the limo to peer out the window.

"I'm guessing it was their lab," I said, feeling utterly sick to my stomach. That is, even more utterly sick to my stomach than I was already feeling. "They must know that the cops are on their way. They're probably getting out and trying to cut down on the evidence."

"Do you think Roger and Samantha were…?"

"They're fine. They have to be fine." Unless Mr. Burke and Troll had gone suicidal like Witch, they probably weren't in the lab when it exploded. And they might have brought along Roger and Samantha, if only as hostages.

I'd gone through too much on this crappy vacation to lose my best friend. It was possible I'd never be able to reconcile with my family, but at least they were going to get out of this alive, and damn it, so were Roger and Samantha. I hadn't vowed many things in my life, but I was vowing this.

We sped down the road, kicking up clouds of dirt in our path. This is what I'd always envisioned driving a limo to be like.

Because of the way my screwed-up mind works, I thought of several amusing and insensitive comments to make about our current situation, but I didn't think they would be taken in the "mental defense mechanism" spirit in which they were intended, so I kept them to myself.

I slowed down around corners because of potential tire shredders, but apart from that we were making great time.

Then, up ahead, was a semi truck. The back of it didn't contain a helpful sign reading "Looney Cyborg Makers, Inc." but I was pretty sure this was a good development. Now I just had to trust that my friends were inside.

The semi was going fast, but the limo could go faster and I drove up right behind it, doing about fifty.

Now what?

"Helen, I need you up front," I said. "You'll have to drive."

"Why?"

"Because I'm getting out."

Helen climbed over into the front, wincing in pain as she bashed her injured foot against the seat in the process.

I didn't want to let the semi out of my sight, but I also didn't want to do something dumb like crash in the middle of a tricky driver-switch maneuver, so I applied the brakes gently enough to avoid catapulting Theresa onto the floor and brought the limousine to a stop. Helen and I switched spots, and then we took off after the semi again.

"What exactly are you planning to do?" Helen asked.

"I'm getting onto the semi."

"How?"

"Still working that out."

"Andrew, you don't even know if they're in there!"

"They're either in there or they were in the explosion. I'm just trying to hope for the best."

It took about a minute to catch up to the semi. I wasn't sure if the occupants knew they were being followed.

"Get as close behind it as you can without ramming it," I instructed.

"You're not going to jump, are you?"

"Still working that out. But yes."

"No!"

"I'm not letting Roger die in there! You have no idea what they're doing to people, even their own people. They're turning them into cyborgs."

"I beg your pardon?"

"Cyborgs. Half-human, half-machine."

"I know what cyborgs are, I just mean… I beg your pardon?"

"I'll explain it later." I rolled down the passenger-side window. "Okay, I'm going to climb out on top of the limo and then out onto the front hood. When you get close enough to the semi, I'm going to jump onto the back."

"Andrew, that's crazy!"

"I don't have any choice!"

"Sure you do." Helen applied the brakes. "Let me stop the car, and then you can get on the hood."

"Oh. Yeah. That's much better. Thanks."

When the car stopped, I threw open the passenger door and got out. Joe barked in what I assume was support for my cause. "Make sure the kids know never, ever to do this," I said, shutting the door and climbing onto the front hood.

Helen resumed driving. None of the insane things I'd done in my life up to this point including jumping from moving vehicles, so it would be nice to add a new experience to my résumé.

It wasn't long before we caught up to the semi again. I inched my way closer to the edge of the front, not feeling particularly secure in my balance. I hoped my missing pinky wouldn't be a liability.

I waved for Helen to move closer to the semi. Now about two feet separated the vehicles. If the driver of the semi suddenly decided to slam on his brakes, I was going to be extraordinarily squished.

Okay, you'll be fine. You can do this. You've seen it in hundreds of movies. The only thing those actors have that you don't are stunt doubles and CGI effects.

Helen got closer. I moved into a squatting position, promptly lost my balance, and very nearly took a dive right off the front of the limousine. I managed to steady myself and recover from my heart attack, and then I got myself back into the squatting position.

It really wasn't that bad of a jump. Hell, if she got any closer, I could step across. No problem. Piece of cake.

Either the semi slowed down or Helen sped up. The front of the limousine hit the back of the semi, not hard enough to do any damage but hard enough to give the limo one hell of a jolt.
