The route we took this time was different still from the last couple of trips I’d made. We used a new doorway to the basement level—this one a wooden panel in a side hallway in the main building—and descended a narrower, steeper staircase. Once we were in the basement, we walked a maze through limestone hallways. I was beginning to think the labyrinth on the floor was more than just decoration. It served as a pretty good symbol of what lay beneath the convent.

Despite how confusing it was, Scout clearly knew the route, barely pausing at the corners, her speed quick and movements efficient. She moved silently, striding through the hallways and tunnels like a woman on a mission. I stumbled at a half run, half walk behind her, just trying to keep up. My speed wasn’t much helped by my stomach’s rolling, both because we were actually going into the basement again—by choice—and for the reason we were going there.

Because I was her mission.

Or so I assumed.

“You could slow down a little, you know.”

“Slowing down would make it harder for me to punish you by making you keep up,” she said, but came to a stop as we reached the dead end of a limestone corridor that ended in a nondescript metal door.

“Why are you punishing me?”

Scout reached up, pulled a key from above the threshold, and slipped it into the lock. When the door popped open, she put back the key, then glanced at me. “Um, you abandoned me for the brat pack?”

“Abandoned is a harsh word.”

“So are they,” she pointed out, holding the door open so I could move inside. “The last time you hung out with them, they put you in the hospital.”

“That was actually your fault.”

“Details,” she said.

My feet still on the limestone, hand on the threshold of the door, I peeked inside. She was leading me into an old tunnel. It was narrow, with an arched ceiling, the entire tunnel paved in concrete, narrow tracks along the concrete floor. Lights in round, industrial fittings were suspended from the ceiling every dozen yards or so. The half illumination didn’t do much for the ambience. A couple of inches of rusty water covered the tracks on the floor, and the concrete walls were covered with graffiti—words of every shape and size, big and small, monotone and multicolored.

“What is this?”

“Chicago Tunnel Company Railroad,” she said, nudging me forward. I took a step into dirty water, glad I’d worn boots for my shopping excursion, and glad I still had on a jacket. It was chilly, probably because we were underground.

“It’s an old railroad line,” Scout said, then stepped beside me. Cold, musty air stirred as she closed the door behind us. Somewhere down the line, water dripped. “The cars used to move between downtown buildings to deliver coal and dump ash and stuff. Parts of the tunnel run under the river, and some of those parts were accidentally breached by the city, so if you see a tsunami, find a bulkhead and make a run for it.”

“I’ll make a point of it.”

Scout reached into her messenger bag and pulled out two flashlights. She took one, then handed me the second. While the tunnels were lit, it made me feel better to have the weight in my hand.

Flashlights in hand, we walked. We took one branch, then another, then another, making so many turns that I had no clue which direction we were actually moving in.

“So this mark thing,” I began, as we stepped gingerly through murky water. “What is it, exactly?”

“They’re called darkenings. We all have them,” Scout answered, the beam of light swinging as she moved. “All the members of the ‘Dark Elite,’” she flatly added, using her hands, flashlight and all, to gesture some air quotes. “That’s what some of the Reapers call us—all of us—who have magic. Elite, I guess, because we’re gifted. They think we’re special, better, because we have magic. And dark because the darkenings are supposed to appear when the magic appears. Well, except in your case.” She stopped and looked at me. “Still no powers, right?”

“Not that I’m aware of, no. Is that why we’re down here? Are you going to prod me or poke me or something, to figure out if I have secret powers? Like a chick on an alien spacecraft?”

“And you think I’m the odd one,” she muttered. “No, Scully, we aren’t going to probe you. We’re just going to talk to the Adepts and see what they have to say about your new tat. No bigs.” She shrugged nonchalantly, then started walking again.

Ten or fifteen minutes later, Scout stopped before a door made up of giant wooden beams, two golden hinges running across it, an arch in the top. A large numeral “3” was elegantly carved into the lintel above the door. And on the door was the same symbol I’d seen in the model room—a circle with a Y inside it.

This was Enclave Three, I assumed.

Scout flipped off her flashlight, then held out her hand; I pressed my flashlight into her palm. She flicked it off and deposited them both back in her messenger bag.

“Okay,” she said, looking over at me. “I suppose I should prep you for this. The other seven Adepts in ET should be here. Katie and Smith are our Varsity Adepts. You remember what that means?”

“They’re the college kids,” I answered. “And Junior Varsity is high school. You just told me on Friday.”

“You’ve brat-packed since then,” she muttered. “Your IQ has probably dropped.”

I gave her a snarky look.

“Anywho,” she said, ignoring the look, “Katie’s a manipulator. Literally and figuratively. You know, in history, when they talk about the Salem witch trials, about how innocent girls and boys were convinced to do all these horrible things because some witch made them?”

I’d read The Crucible in English last year (probably just like every other sophomore), so I nodded.

“Yeah, well, they probably were convinced. That stuff wasn’t a myth. Katie’s not a wicked witch or anything, but she’s got the same skills.”

“Well, that’s just downright disturbing,” I said.

“Yeah.” She nodded, then patted my arm. “Sleep well tonight. Anyway, Katie manipulates, and Smith—and, yes, that’s his first name—levitates. He lifts heavy stuff, raises things in the air. As for JV, you know me, Michael and Jason, obvs, and there are three more. Jamie and Jill, those are the twins. Paul’s the one with the curls.”

“You said you were a spellcaster?”

“Binder. Spellbinder.”

“Okay. So what are these guys? Michael and the rest of them. What can they do?”

“Oh, sure, um”—she shifted her feet, her gaze on the ceiling as she itemized—“um, Jamie and Jill have elemental powers. Fire and ice.”

“They have firespell?” I wondered aloud.

“Oh, sorry, no. Jamie can manipulate fire, literally—like a firestarter. Set stuff ablaze, create smoke, general pyromania. She can work with the element without getting burned. Firespell is different—it’s not about fire, really, but about power, at least we think. There aren’t any Adepts with firespell, so we kind of go off what we’ve seen in action. Anywho, you put Jamie, Jill, and me together, and we’re one medieval witch,” she said, with what sounded like a fake laugh. “Paul is a warrior. A man of battle. Ridiculous moves, like something out of a kung fu movie. Michael is a reader.”

“What’s a reader?”

“Well, I bind spells, right? I take words of power, charms and I translate them into action, like the house I showed you.”

I nodded.

“Michael reads objects. He can feel them out, determine their history, hear what they’re saying about things that happened, conditions.”

“Well that’s . . . weird. I mean cool, but weird.”

She shrugged. “Unusual, but handy. Architecture speaks to him. Literally.”

“And for all that, you two still aren’t dating.”

She narrowed her gaze. “I’m not sure I should let you two talk to each other anymore. Now, are you done procrastinating? Can we get on with this?”

“I’m not procrastinating,” I said, procrastinating. “What about Jason?” I already suspected, of course, what Jason’s magic was. But he hadn’t exactly confirmed it, and my own suspicions—that he had some kind of animal-related power—were strange enough that I wasn’t ready to put them out there. On the other hand, how many teenage boys growled when they were attacked?

Okay, when you put it that way, it actually didn’t sound that rare.

Scout dropped her gaze and fiddled with her messenger bag. “Jason’s power isn’t for me to tell. If he’s ready for that, he’ll tell you.”

“I—I have an idea.”

She went quiet and slowly lifted her gaze to mine. “An idea?”

We looked at each other for a minute, silently, each assessing the other: Do you know what I know? How can I confirm it without giving it away?

“I’ll let you talk to him about that,” she finally said, raising her hand to the door. “Are you ready now?”

“Are they gonna wig out that you’re bringing me?”

“It’s a good possibility,” she said, then rapped her fist in a rhythmic pattern. Knock. Knock, knock. Bang. Knock.

“Secret code?” I asked.

“Warning,” she said. “Jamie and Paul are dating. In case we’re early, I don’t want to walk in on that.”

The joke helped ease my nerves, but only a little. As soon as she touched the door handle, my stomach began rolling again.

“Welcome to the jungle,” she said, and opened the door.

The jungle was a big, vaulted room, of a quality I wouldn’t have expected to see in an abandoned railway tunnel far beneath Chicago. It looked like a meeting hall, the walls covered in paintings made up of tiny, mosaic tiles, the ceilings girded with thick, wooden beams. It had the same kind of look as the convent—big scale, careful work, earthy materials. The room was empty of furniture—completely empty except for the seven kids who’d turned to stare at the door when it opened. There were three girls and four guys, including Michael and Jason.

Jason of the deadly blue eyes and currently frigid stare.

The room went completely silent, all fourteen of those eyes on us as we stepped into the room. Scout squeezed my hand supportively.

Silently, they moved around and formed a semicircle facing us, as if containing a threat. I shuffled a little closer to Scout and surveyed the judges.

Jamie and Jill were the obvious twins, both tallish and lanky, with long auburn hair and blue eyes. Paul was tall, lean, coffee-skinned and very cute, his hair a short mop of tiny, spiral curls.

The guy and girl in the middle, who looked older than the rest of them—early college, maybe—stepped forward, fury on their faces. I guessed these were Katie and Smith. Katie was cheerleader cute, with a bob of shoulder-length brown hair, green eyes, a long T-shirt, and ballet flats paired with jeans. Smith—shaggy brown hair pasted to his forehead emo-style—wore a dingy, plaid shirt. He was the rebel type, I assumed.

“Green,” he bit out, “you’d better have a damn good reason for calling us in and, more important, for bringing a regular in here.”

Okay, so pasty hair was clearly not impressed with me.

Scout crossed her arms, preparing for battle. “A,” she said, “this is Lily Parker, the girl who took a hit of firespell to save us and wound up in a paper nightgown in the LaSalle Street Clinic because of it. Ring any bells?”

I actually took a hit because I’d tripped, but since the Adepts’ expressions softened after she passed along that little factoid, I kept the truth to myself.

“B,” Scout continued, “I have a damn good reason. We need to show you something.”

Katie spoke up. “You could have showed us something without her being here.”

“I can’t show you what I need to show you without her being here.” Her explanation was met with silence, but she kept going. “You have to know that I wouldn’t have brought her here if it wasn’t absolutely necessary. Trust me—it’s necessary. The Reapers have already seen her, and they already think she’s associated with us. They get ambitious and come knocking on our door tonight, and she’s in even more trouble. She’s here as a favor to us.”

Katie and Smith glanced at each other, and then she whispered something to him.

“Five minutes,” Smith finally said. “You have five minutes.”

Scout didn’t need it; it took two seconds for her to drop the bomb. “I think she might be one of us.”

Silence, until Katie made a snorty, skeptical sound. “One of us? Why in God’s name would you think she’s one of us? She’s a regular, and getting hit with a blast isn’t going to change that.”

“Really?” Scout asked. “You don’t think getting hit with a dose of firespell is going to have an effect? Given that we’re all bouncing around Chicago with magical gifts, that’s kind of a narrow- minded perspective, isn’t it, Katie?”

Katie arched an arrogant brow at Scout. “You need to watch your step, Green.”

Michael stepped forward, hands raised in peace. “Hey, if there’s something we need to figure out here, the fewer preconceptions, the better. Scout, if you have something you need us to see, you’d better show it now.”

Scout glanced over at me, nodded her head decidedly, then spun her finger in the air.

“Turn around,” she said. I glanced around the room, not entirely eager to pull up my shirt before an assemblage of people I didn’t know—and a boy I potentially wanted to know better. But it needed to be done, so I twisted around, pulled my shirt from the waist of my skirt, and lifted it just enough to show the mark across my lower back.
