And ran smack into Robbie, standing outside the door.

He grabbed my shoulders as I screamed and started hitting him, barely conscious of what I was doing. He bore the attack wordlessly, simply holding me in place, until I collapsed against him and buried my head in his chest. And he held me as I sobbed out my fear and anger.

At last, the tears stopped, leaving me drained and utterly exhausted. I sniffed and backed away, wiping my eyes on my palm, shaking. Robbie still stood there quietly, his shirt damp with my tears. The door to Ethan’s bedroom was shut, but I could hear faint thumps and cackling laughter beyond the door.

I shivered, looking up at Robbie. “Ethan is really gone?” I whispered. “He’s not just hiding somewhere? He’s really gone?”

Robbie nodded gravely. I looked at Ethan’s bedroom door and bit my lip. “Where is he now?”

“Probably in Faeryland.” Stated so simply, I almost laughed from the sheer ridiculousness of it all. Ethan had been stolen by faeries and replaced with an evil doppelg?nger. Faeries kidnapped my brother. I was tempted to pinch myself to see if this was a twisted dream or hallucination. Maybe I had fallen into a drunken stupor on the couch. On impulse, I bit the inside of my cheek, hard. The sharp pain and taste of blood told me this was, indeed, real.

I looked to Robbie, and his grave expression banished the last of my doubts. A sick feeling rose to my stomach, making me nauseous and afraid.

“So…” I swallowed and forced myself to be calm. Okay, Ethan was kidnapped by faeries; I could deal with this. “What do we do now?”

Robbie raised one shoulder. “That’s up to you, princess. There are human families that have raised changelings as their own, though they are usually unaware of the child’s true nature. Generally speaking, if you feed it and leave it alone, it will settle into its new home without too much trouble. Changelings make a nuisance of themselves at first, but most families adapt.” Robbie grinned, but it was an attempt at lightheartedness rather than humor. “Hopefully, your folks will think he’s just going through a late terrible twos.”

“Robbie, that thing bit me, and probably made Mom slip and fall in the kitchen. It’s more than a nuisance, it’s dangerous.” I glared at Ethan’s closed door and shuddered. “I want it gone. I want my brother back. How do we get rid of it?”

Robbie sobered. “Well, there are ways of getting rid of changelings,” he began, looking uncomfortable. “One old method is to brew beer or cook stew in eggshells, and that will make the changeling comment on the weirdness of it. But that method was for infants who’d been switched—since the baby was too young to speak, the parents knew that the impostor was a changeling and the real parents had to take it back. I don’t think it’ll work for someone older, like your brother.”

“Great. What’s another way?”

“Er, the other way is to beat the changeling near to death, until the screams force the fey parents to return the real child. Barring that, you could stick him in the oven and cook him alive—”

“Stop.” I felt sick. “I can’t do any of those things, Robbie. I just can’t. There has to be another way.”

“Well…” Rob looked hesitant and scratched the back of his neck. “The only other way is to travel into the faery lands and take him back. Bringing the real child into the home again will force the changeling to leave. But…” He paused, as if on the verge of saying something, only to think better of it.

“But what?”

“But…you don’t know who took your brother. And without that knowledge, you’ll just be walking in circles. And, if you’re wondering, walking in circles in Faeryland is a very, very bad idea.”

I narrowed my eyes. “I don’t know who took him,” I agreed, staring hard at Robbie, “but you do.”

Robbie shuffled nervously. “I have a guess.”

“Who?”

“It’s just a guess, mind you. I could be wrong. Don’t go jumping to conclusions.”

“Robbie!”

He sighed. “The Unseelie Court.”

“The what?”

“The Unseelie Court,” Robbie repeated. “The Court of Mab, Queen of Air and Darkness. Sworn enemies of King Oberon and Queen Titania. Very powerful. Very nasty.”

“Wait, wait, wait.” I held up my hands. “Oberon? Titania? Like from A Midsummer Night’s Dream? Aren’t those just ancient myths?”

“Ancient, yes,” Robbie said. “Myths, no. The faery lords are immortal. Those who have songs, ballads, and stories written about them never die. Belief, worship, imagination—we were born of the dreams and fears of mortals, and if we are remembered, even in some small way, we will always exist.”

“You keep saying ‘we,’” I pointed out. “As though you’re one of those immortal faeries. As though you’re one of them.” Robbie smiled, a proud, impish smile, and I gulped. “Who are you, anyway?”

“Ah, well.” Robbie shrugged, trying to look modest and failing entirely. “If you’ve read A Midsummer Night’s Dream, you might remember me. There was this unfortunate incident, completely unplanned, where I gave someone a donkey’s head and made Titania fall in love with him.”

I ran through the play in my mind. I’d read it in the seventh grade, but had forgotten most of the plot. There were so many characters, so many names to sift through, people falling in and out of love so often it was ridiculous. I remembered a few human names: Hermia, Helena, Demetrius. On the faery side, there was Oberon and Titania and…

“Shit,” I whispered, falling back against the wall. I stared at Robbie with new eyes. “Robbie Goodfell. Robin…you’re Robin Goodfellow.”

Robbie grinned. “Call me Puck.”

PUCK. THE PUCK WAS STANDING in my hallway.

“No way,” I whispered, shaking my head. This was Robbie, my closest friend. I would’ve known if he was an ancient faery. Wouldn’t I?

Frighteningly, the more I thought about it, the more likely it seemed. I’d never seen Robbie’s house, or his parents. The teachers all loved him, though he never did a lick of school-work and slept through most of the classes. And strange things happened when he was around: mice and frogs ended up in desks, or names were switched around on term papers. Though Robbie Goodfell thought these scenarios absolutely hilarious, no one ever suspected him.

“No,” I muttered again, backing away toward my room. “That’s impossible. Puck is a legend, a myth. I don’t believe it.”

Robbie gave me that eerie smile. “Then, princess, by all means, let me assure you.”

His arms rose from his sides, as if he might levitate into the air. From downstairs, I heard the front door creak open, and I hoped Mom and Luke weren’t home yet. Yeah, Mom, Ethan’s turned into a monster and my best friend thinks he’s a faery. How was your day?

An enormous black bird swooped into the hallway. I yelped and ducked as the raven, or crow or whatever it was, made a beeline straight for Robbie and perched on his arm. They watched me, the pair of them, with glittering eyes, and Robbie smiled.

A rush of wind, and suddenly, the air was filled with screaming black birds, swooping in from the open door. I gasped and ducked as the cloud of ravens filled the hallway, their raucous cries nearly deafening me. They swirled around Robbie, a tornado of beating wings and sharp claws, tearing at him with talons and beaks. Feathers flew everywhere, and Robbie disappeared within the swirling mass. Then, as one, the birds scattered, flying out the open door as swiftly as they had come. As the last bird swooped outside, the door slammed behind it, and silence descended once more. I caught my breath and glanced at Rob.

Robbie was gone. Only a swirl of black feathers and dust motes remained in the place where he’d stood.

It was too much. I felt my sanity unravel like frayed cloth. With a choked scream, I turned and fled into my room, slamming the door behind me. Flinging myself under my bedcovers, I put the pillow over my head and shook, hoping that when I woke up, things would be normal.

My door opened, and the sound of wings fluttered into my room. I didn’t want to look and pulled the covers tighter around me, willing the nightmare to end. I heard a sigh, and footsteps padded over the floor.

“Well, I tried to warn you, princess.”

I peeked out. Robbie stood there, looking down at me, a pained smile on his face. Seeing him, I felt relieved, angry, and terrified at the same time. I threw off the covers and sat up, narrowing my eyes as I stared at him. Robbie waited, hands in the pockets of his jeans, as if daring me to contradict him some more.

“You really are Puck?” I said finally. “The Puck? Like in the stories?”

Robbie/Puck gave a little bow. “The one and only.”

My heart was still pounding. I took a deep breath to calm it and glared at the stranger in my room. My emotions churned; I didn’t know what to feel. I settled on anger; Robbie had been my best friend for years, and he never saw fit to share his secret with me. “You could have told me sooner,” I said, trying not to sound hurt. “I would have kept your secret.” He only smirked and raised an eyebrow, infuriating me even more. “Fine. Go back to Faeryland, or wherever you come from. Aren’t you supposed to be Oberon’s jester or something? Why were you hanging around me so long?”

“You wound me, princess.” Robbie sounded anything but hurt. “And after I made up my mind to help you get your brother back.”

My anger vanished instantly, replaced with fear. With all the talk of fey and faery lords, I’d nearly forgotten about Ethan.

I shivered as my stomach twisted into a tight little ball. This still felt like something out of a nightmare. But Ethan was gone, and faeries were real. I had to accept that now. Robbie stood there, gazing at me expectantly. A black feather dropped from his hair, spiraling down to the bed. Gingerly, I picked it up, twirling it in my fingers. It felt solid and real.

“You’ll help me?” I whispered.

He gave me a shrewd look, one corner of his mouth turning up. “Do you know a way into Faery by yourself?”

“No.”

“Then you need my help.” Robbie smiled and rubbed his hands together. “Besides, it’s been a while since I’ve gone home, and nothing ever happens here. Storming the Unseelie Court sounds like fun.”

I didn’t share his enthusiasm. “When do we leave?” I asked.

“Now,” Robbie replied. “The sooner the better. Do you have anything you want to take, princess? You might not be back for a while.”

I nodded, trying to stay calm. “Just give me a minute.”

Robbie nodded and walked into the hallway. I snatched my bright orange backpack and tossed it on the bed, wondering what to take. What did one need for an overnight trip to Faeryland? I grabbed jeans and an extra shirt, a flashlight, and a bottle of aspirin, stuffing them into the pack. Walking down to the kitchen, I tossed in a Coke and a couple of bags of chips, hoping Robbie would know where to find food on the journey. Finally, not even knowing why, I grabbed my iPod, zipping it into the side pocket.

Mom was supposed to take me to the DMV today. I hesitated, biting my lip. What would Mom and Luke think when they found me gone? I’d always followed the rules, never sneaking out—except that one time with Robbie—never staying up past curfew. I wondered what Rob meant when he said we’d be gone “awhile.” Luke might not even notice I’d left, but Mom would worry. Grabbing an old homework sheet, I started to write her a quick note, but stopped, my pen hovering over the paper.

What are you going to tell her? “Dear Mom, Ethan’s been kidnapped by faeries. Gone to get him back. Oh, and don’t trust the Ethan that’s here—he’s really a faery changeling.” It sounded insane even to me. I hesitated, thinking, then scrawled a quick:

Mom, there’s something I have to take care of. I’ll be back soon, I promise. Don’t worry about me. Meghan

I stuck the note on the refrigerator door, trying not to think that I might never see home again. Shouldering the pack, feeling my insides squirm like a nest of snakes, I climbed the stairs.

Robbie waited on the landing, arms crossed over his chest, wearing a lazy grin. “Ready?”

Apprehension tickled my stomach. “Will it be very dangerous?”

“Oh, extremely,” Robbie said, walking up to Ethan’s bedroom door. “That’s what makes it fun. You can die in so many interesting ways—skewered on a glass sword, dragged underwater and eaten by a kelpie, turned into a spider or a rosebush for all time—” He looked back at me. “Well, are you coming or not?”

I noticed my hands were shaking and held them to my chest. “Why are you saying these things?” I whispered. “Are you trying to scare me?”

“Yes,” Robbie replied, unabashed. He paused at Ethan’s door, one hand on the knob, and stared at me. “These are the things you’re going to face, princess. I’m giving you fair warning now. Still think you want to go? My previous offer still stands.”

I remembered the taste of the mistwine, the desperate longing for more, and shivered. “No,” I said quickly. “I won’t leave Ethan with a bunch of monsters. I’ve lost a father already—I won’t lose a brother, as well.”

And then, something occurred to me, something that left me breathless, wondering why I didn’t think of it before. Dad. My heart pounded, recalling half-remembered dreams, where my father vanished beneath a pond and never resurfaced. What if he’d been kidnapped by faeries, as well? I could find Ethan and my dad, and bring them both home!
