“I’m okay now,” I said, lying through my teeth. “Maybe it’s a stomach bug or something.” Yeah, the kind of stomach bug that causes brain cancer. The kind of bug you get when your whole genetic makeup is about to unravel. The bug you get before you die.

“Let’s just go to New York,” I said.

After giving me a long, level look, Fang shrugged and motioned to the Gasman to take off. Reluctantly, he did, and the others followed. “After you,” Fang said, jerking his thumb toward the sky.

Gritting my teeth, I got to my feet and ran shakily, opening my wings and leaping into the air again, half braced for another explosion of pain. But it was okay. I still felt like I might hurl, and I thought about how awful that would be in midair.

“Are you okay?” Nudge asked once we were airborne. I nodded.

“I’ve been thinking about my mom and dad,” she said. Her tawny wings beat in unison with mine, so we just barely missed each other on the downstrokes. “I bet-if they’ve been thinking I died eleven years ago, then I bet they would be pretty happy to see me again, right? I mean, if all this time they wished I had gone home with them and grown up-then they would be pretty happy to see me, wouldn’t they?” I didn’t say anything.

“Unless…” She frowned. “I mean-I guess I’m not what they would be expecting, huh? It’s not my fault or anything, but I mean, I’ve got wings.” Yep, I thought.

“They might not want me if I have wings and am so weird and all,” Nudge said, her voice dropping. “Maybe they just want a normal daughter, and if I’m weird, they wouldn’t want me back anyway. What do you think, Max?”

“I don’t know, Nudge,” I said. “It seems like if they’re your parents, then they should love you no matter what, even if you’re different.”

I thought about how Ella had accepted me just the way I was, wings, weirdness, and all. And Dr. Martinez was always going to be my perfect image of a mom. She’d accepted me too.

Now I was gulping, trying not to cry. Because I hadn’t experienced enough emotion already this morning. I muttered a swear word to myself. After I’d heard Angel cussing like a sailor when she stubbed her toe, my new resolution was to watch my language. All I needed was a six-year-old mutant with a potty mouth.

I thought about how Ella and her mom and I had made chocolate-chip cookies. From scratch. From, like, a bag of flour and real eggs. Not store-bought, not even slice ‘n’ bake. The way they’d smelled when they were baking was in-cred-i-ble. It had smelled like-home. Like what a real home should smell like.

They’d been the best dang cookies I’d ever had.

“Oh, my God,” I muttered, staring at the lights below us. Most of New York City is at the bottom part of a long, thin island- Manhattan Island, actually. You could tell exactly where it began and ended, because suddenly the dark landscape was ablaze with lights. Streaming pearls of headlights moved slowly through the arteries of the city. It looked like every window in every building had a light burning.

“That’s a lot of people,” Fang said, coming up beside me.

I knew what he was thinking: We all tend to get a little claustrophobic, a little paranoid when we’re around lots of people. Not only had Jeb constantly warned us about interacting with anyone for any reason, but there was always the possibility that one of those strangers could suddenly morph into an Eraser.

“Oh, my gosh, oh, my gosh,” Nudge was saying excitedly. “I want to go down there! I want to walk on Fifth Avenue! I want to go to museums!” She turned to me, her face alight with anticipation. “Do we have any money left? Can we get something to eat? Can we, like, go shopping?”

“We have some money,” I told her. “We can get something to eat. But remember, we’re here to find the Institute.”

Nudge nodded, but I could tell half of my words had gone right out her other ear.

“What’s that sound?” Iggy asked, concentrating. “It’s music. Is there music below us? How could we hear it, way up here?”

Central Park was a big, relatively dark rectangle below us. At one end, in a clearing, I could see an enormous crowd of people. Huge floodlights were shining over them.

“I think it must be a concert,” I told Iggy. “In the park. An outdoor concert.”

“Oh, so cool!” Nudge said. “Can we go? Please, Max, please? A real concert!” If it’s possible for someone to bounce up and down with excitement while flying, Nudge was doing it.

The park was pretty dark. There were hundreds of thousands of people down there. Even Erasers would have a hard time finding us in that crowd.

I made an executive decision. “Yes. Try to come down right behind a floodlight’s beam, so we won’t be seen.”

We landed silently among a group of thick-trunked oaks. We took a moment to shake out our legs, and fold in our wings and cover them with windbreakers. After a quick head count, I led the way toward the crowd, trying to look casual, like, Fly? Me? Nah.

The music was unbelievably loud: Speakers taller than Iggy were stacked on top of one another, three high. To me it felt as if the actual ground was vibrating.

“What concert is this?” Iggy asked, yelling in my ear.

I peered over tens of thousands of heads to see the raised stage. Thanks to my raptorlike vision, I had no trouble making out the musicians. And a banner that said Natalie and Trent Taylor. “It’s the Taylor Twins,” I reported, and most of the flock whooped and whistled. They loved the Taylor Twins.

Angel kept close to me, her small hand in mine, as we stood among the crowd. We were enough on the edge that we avoided the sardine effect of the people closer to the stage. I think we all would have freaked out if we’d been that hemmed in, that unable to move. Iggy put the Gasman on his shoulders and gave him his lighter to burn, like thousands of other people. The Gasman swayed in time to the music, holding the lighter high.

Once he looked down at me, and his face was so full of happiness I almost started crying. How often had I seen him look like that? Like, twice? In eight years?

We listened to Natalie and Trent until the concert ended. As soon as the rivers of people began to flow past us, we melted into the shadows of the trees. The branches above us were thick and welcoming. We flew up into them, settling comfortably.

“That was awesome,” Nudge said happily. “I can’t believe how many people there are, all crowded into one place. I mean, listen… There’s no silence, ever. I can hear people and traffic and sirens and dogs barking. I mean, it was always so quiet back at home.”

“Too quiet,“ said the Gasman.

“Well, I hate it,” Iggy said flatly. “When it’s quiet, I can tell where the heck things are, people are, where echoes are bouncing off. Here I’m just surrounded with a thick, smothering wall of sound. I want to get out of here.”

“Oh, Iggy, no!” Nudge cried. “This place is so cool. You’ll get used to it.”

“We’re here to find out what we can about the Institute,” I reminded both of them. “I’m sorry, Iggy, but maybe you’ll get a little more used to it soon. And Nudge, this isn’t a pleasure trip. Our goal is to find the Institute.”

“How are we gonna do that?” Angel asked.

“I have a plan,” I said firmly. God, I was really going to have to get all this lying under control.
