“Don’t beat yourself up about it. It happens to me all the time. You know what’s weird, though? Why didn’t the vampire just eat me right away?”

“Perhaps it had gorged itself earlier and was planning on saving you for another meal,” Nathaniel said.

I shook my head. “I don’t think so. Don’t you think it would have at least drained me a little so I would be more compliant? It seemed it wanted to take me somewhere.”

“To its master, perhaps?” Nathaniel asked.

“That would be logical. If it was fetching me for a higher-ranking vampire, then it probably wouldn’t want to offend its boss by taking my blood.”

“Which then begs the question of why the vampire wanted you specifically.”

“Yeah. That’s not really a question I’d enjoy answering. I’m sure I won’t like the result, whatever it is.” I looked around. “Where’s my sword?”

“There,” Nathaniel said, pointing back toward the place where the vampire had grabbed me. “I could not lift it. It would not allow me to touch it.”

“But you gave me that sword,” I said. “It belonged to your father.”

“The sword seems to have given itself to you completely.”

Or maybe the sword of Lucifer recognized the blood of the Morningstar’s sworn enemy, but I wasn’t going to say that. Not yet, anyway. Not until I was 100 percent sure—but I was getting there. I wondered how Nathaniel would react if I was right. It might unhinge him. He put a lot of stock in the quality of his bloodline.

I fetched the sword, and then jogged back to Nathaniel. “Let’s get home.”

There was the distinct click of a safety being released behind us.

“You’ve got to be kidding me,” I said.

We turned around slowly to face Bryson’s furious glare. He held a semiautomatic pistol, and it was pointed at me.

“What is your problem?” I asked. “Has it escaped your attention that the city has been overrun by vampires?”

“Sokolov wants you brought in. So you will be brought in,” Bryson said. “He’s had enough of your defiance.”

“Does he know you tried to shoot us out of the sky earlier?” I asked, thinking of Nathaniel’s shredded wing, our terrifying fall through the air. “Or am I wanted dead or alive?”

Bryson smiled briefly. “I am supposed to bring you in alive. But if there were an unfortunate accident, I believe Sokolov would understand.”

I was suddenly angry, so angry that I didn’t know what to do with all that energy. I was sick to death of being hounded by the shortsighted Agency when there were more important problems at hand.

My magic leapt to the fore, and my power pulsed through the night.

Nathaniel put his hand on my shoulder. “Ease down, unless you wish to destroy the bridge while we are still on it.”

The darkness was filled with light, and it was coming from me.

“Hear this, Bryson,” I said, and my voice was different. There was a power and a promise in it. “If you attempt to take, threaten or harm me or my friends again, then I will destroy you so utterly that the world will not even recall that you ever existed.”

I could crush him like a bug. His gun was a toy, a meaningless thing that he used to feel powerful. I blasted his hand with nightfire and the weapon clattered to the ground. I stalked toward him, and Bryson, super-soldier of the Agency, backed away from me.

“You have been broken by one of my kind before,” I said. “But obviously not enough. The pain you felt then will be nothing compared to what horrors you will suffer at my hands.”

I could do it. I knew I could. I could make him hurt. The power was in me. There was a dark shadow in my heart, and it urged me onward.

“Madeline!” Nathaniel said behind me, and his hand roughly pulled me back. “Madeline! You are not yourself. Think.”

He gave me a little shake, and I nearly blasted him before his urgent tone got through to me. The darkness receded as suddenly as it had emerged.

“What…what was that about?” I gasped. I looked to my left. Bryson had fled. Which was good. I didn’t think I could live with myself if I’d done all the horrible things I’d been contemplating.

“You must be careful,” Nathaniel said. “As more of Lucifer’s power is revealed in you, so, too, is his darkness.”

I had felt hints of this before, a sinister undertone to the magic that was emerging slowly inside me. But I’d always thought I was in control of it, that my own personality would overcome any darker impulses. Now I wasn’t so sure.

I tipped my head forward to Nathaniel’s shoulder for a moment, weary beyond belief. Now that the burst of power had receded, my whole being just wanted to lie down and rest. But I wouldn’t be able to rest until we were home.

“Let’s go,” I said, lifting my head. Nathaniel nodded.

It took us most of the night. My weariness was extreme, and while the vampires avoided the path along the lake, there were plenty of other things that did not—demons, mostly, roaming for stragglers.

We avoided the creatures if we could, always mindful of the fact that neither of us could fly. When we could not avoid conflict Nathaniel’s newfound strength and speed tended to keep the encounters short. As we got farther away from the Loop, we felt safer cutting west and then north again on the city streets. As the day approached, we were on Clark, the distinctive curve of Wrigley Field’s façade before us.

The streets were so quiet. Many people had obviously fled, and any who had stayed behind were safely tucked inside their apartments and condos, cowering behind furniture stacked against doors.

In their hands would be Mace and hair spray and fire extinguishers and guns, for those who believed in that sort of thing. Others would be on their knees, hands folded and eyes shut tight, calling the name of their chosen savior.

All around us was the debris of a fallen world—a smashed cell phone, a Starbucks cup, a dropped scarf, a suitcase that had broken open and spilled its contents all over the street.

Inside the case were the things its owner had considered important—a wedding photo in a silver frame, the glass shattered; wool socks rolled in multicolored balls; lacy underwear; designer jeans; a stack of Fiber One bars; a jewelry roll that had already been stripped of anything valuable; a deck of cards.

Farther down the street was a stuffed dinosaur, trampled in some mad stampede. The sight of it made me painfully sad. The child who’d dropped that stuffed toy would be crying, confused and scared, and now lacked even the simple, basic comfort of their favorite friend. Wherever that child was, the night would be a little darker, a little colder, without their dinosaur. Everyone knows dinosaurs keep the monsters away.

The bars on Clark Street advertised drink specials, live bands, half-priced hamburgers. The flags above the storefronts fluttered pathetically in the wind, the logos of the Cubs and the Blackhawks, the Bulls and the Bears. The red stars of the Chicago city flag looked like bloodstained hands lined up in a row.

Yesterday all of these things had seemed desperately important—whether or not the Hawks beat the Wings, or your friend was late to the bar. Today everyone was just trying to hold on, to not have to witness their family being devoured by vampires.

All of the edifices of humanity—the roads and the cars, the fast-food joints and the parking meters, the smartphones and the bicycles, lazy days at the ballpark, afternoons grilling while the kids scoot up and down the sidewalk, boutiques and thrift stores, Italian ice and Italian beef, cheering for a touchdown in a bar with a mouthful of nachos and beer sloshing over the table, complaining about the traffic, complaining about the taxes, complaining about the mayor and the garbage pickup and the noisy college kids having a party, library books and comic books, kissing in the kitchen or on the front porch or in the shadow of a tower—all of these things had been swept away. Maybe someday there would be a new normal. But for now everything that had made Chicago was gone.

“Madeline,” Nathaniel said. His hand was at my elbow. “Madeline, we are nearly home.”

I realized I stood in the middle of Clark Street with the dinosaur clutched to my chest.

“Madeline,” Nathaniel said again, and put his arm around my shoulder, made me move my feet.

“How can anything be the same again?” I said.

“This is what happens during war,” Nathaniel said, and his voice was gentle, so like Gabriel’s that my heart ached.

“The war is here because of me. These people suffered because of me, because Azazel hated me so much that he needed to send the monster to my doorstep.”

“If it was not Chicago, it would have been some other city, some other innocents. And you would have felt just as responsible, because Azazel is your father.”

I squeezed the stuffed dinosaur in my hands. “You’re right. I would have. But that knowledge doesn’t make this any easier. He destroyed my home, the city I loved.”

I’m not sure how we got home. The last mile or so was a blur. I remember ringing the doorbell—my keys had gone missing somewhere in the night—and Samiel opening the door, his face white and drawn with worry. I fell into his arms, and then everything was black.

When I opened my eyes again I was in my own bed. The sun streamed through the windows, and Beezle sat on the pillow next to me, watching me sleep.

“Do you know that your hair has grown about four inches while you slept?”

I sat up and rubbed my eyes, and the stuffed dinosaur rolled onto my lap.

“You were clutching that filthy thing for two days,” Beezle said. “No one could pry it out of your hands. I wiped it down with antibacterial gel as best I could so that you wouldn’t get botulism all over your sheets.”

“I was asleep for two days?” I asked.

“Yes. And have I mentioned your unusual hair growth, and the fact that Nathaniel’s essence is different from what it was when he left?”

I went still. I hoped Beezle hadn’t blabbed about the change in Nathaniel.
