“When we leave here, this loop will close behind us. It’s possible you may never be able to return to the time you came from. At least, not easily.”

“There’s nothing for me there,” I said quickly. “Even if I could go back, I’m not sure I’d want to.”

“You say that now. I need you to be sure.”

I nodded, then stood.

“Where are you going?” she asked.

“For a walk.”

I didn’t go far, just around the perimeter of the neat yard in a slow shuffle, watching the sky, clear now, a billion stars spread across it. Stars, too, were time travelers. How many of those ancient points of light were the last echoes of suns now dead? How many had been born but their light not yet come this far? If all the suns but ours collapsed tonight, how many lifetimes would it take us to realize that we were alone? I had always known the sky was full of mysteries—but not until now had I realized how full of them the earth was.

I came to the place where the path emerged from the woods. In one direction lay home and everything I knew, unmysterious and ordinary and safe.

Except it wasn’t. Not really. Not any more. The monsters had murdered Grandpa Portman, and they had come after me. Sooner or later, they would again. Would I come home one day to find my dad bleeding to death on the floor? My mom? In the other direction, the children were gathering in excited little knots, plotting and planning, for the first time any of them could remember, for the future.

I walked back to Emma, still poring over her massive book. Miss Peregrine was perched next to her, tapping with her beak here and there on the map. Emma looked up as I approached.

“I’m sure,” I said.

She smiled. “I’m glad.”

“There’s just one thing I have to do before I go.”

*   *   *

I made it back to town just before dawn. The rain had finally eased, and the beginning of a blue day was percolating on the horizon. The main path looked like an arm with the veins stripped out, long slashes where flooding had washed the gravel away.

I walked into the pub and through the empty bar and up to our rooms. The shades were drawn and my father’s door was closed, which was a relief because I hadn’t yet figured out how to say what I needed to tell him. Instead I sat down with pen and paper and wrote him a letter.

I tried to explain everything. I wrote about the peculiar children and the hollows and how all of Grandpa Portman’s stories had turned out to be true. I told him what had happened to Miss Peregrine and Miss Avocet and tried to make him understand why I had to go. I begged him not to worry.

Then I stopped and read over what I’d written. It was no good. He would never believe it. He’d think I’d lost my mind the way Grandpa had, or that I’d run away or been abducted or taken a nosedive off the cliffs. Either way, I was about to ruin his life. I wadded up the paper and threw it in the trash.

“Jacob?”

I turned to see my father leaning in the doorjamb, bleary-eyed, hair tangled, dressed in a mud-splashed shirt and jeans.

“Hi, Dad.”

“I’m going to ask you a simple, straightforward question,” he said, “and I’d like a simple, straightforward answer. Where were you last night?” I could tell he was struggling to maintain his composure.

I decided I was done lying. “I’m fine, Dad. I was with my friends.”

It was like I’d pulled the pin on a grenade.

“YOUR FRIENDS ARE IMAGINARY!” he shouted. He came toward me, his face turning red. “I wish your mother and I had never let that crackpot therapist talk us into bringing you out here, because it has been an unmitigated disaster! You just lied to me for the last time! Now get in your room and start packing. We’re on the next ferry!”

“Dad?”

“And when we get home, you’re not leaving the house until we find a psychiatrist who’s not a complete jackass!”

“Dad!”

I wondered for a moment if I would have to run from him. I pictured my dad holding me down, calling for help, loading me onto the ferry with my arms locked in a straightjacket.

“I’m not coming with you,” I said.

His eyes narrowed and he cocked his head, as if he hasn’t heard properly. I was about to repeat myself when there was a knock at the door.

“Go away!” my dad shouted.

The knock came again, more insistent this time. He stormed over and flung it open, and there at the top of the stairs stood Emma, a tiny ball of blue flame dancing above her hand. Next to her was Olive.

“Hullo,” Olive said. “We’re here to see Jacob.”

He stared at them, baffled. “What is this ...”

The girls edged past him into the room.

“What are you doing here?” I hissed at them.

“We only wanted to introduce ourselves,” Emma replied, flashing a big smile at my dad. “We’ve come to know your son rather well of late, so we thought it only proper that we should pay a friendly call.”

“Okay,” my father said, his eyes darting between them.

“He’s really a fine boy,” said Olive. “So brave!”

“And handsome!” Emma added, winking at me. She began to roll the flame between her hands like a toy. My father stared at it, hypnotized.

“Y-yes,” he stammered. “He sure is.”

“Do you mind if I slip off my shoes?” Olive asked, and without waiting for an answer she did, and promptly floated to the ceiling. “Thanks. That’s much more comfortable!”

“These are my friends, Dad. The ones I was telling you about. This is Emma, and that’s Olive, on the ceiling.”

He staggered back a step. “I’m still sleeping,” he said vaguely. “I’m so tired ...”

A chair lifted off the floor and floated over to him, followed by an expertly wrapped medical bandage bobbing through the air. “Then please, have a seat,” Millard said.

“Okay,” my dad replied, and he did.

“What are you doing here?” I whispered to Millard. “Shouldn’t you be lying down?”

“I was in the neighborhood.” He held up a modern-looking pill bottle. “I must say, they make some marvelously effective pain tablets in the future!”

“Dad, this is Millard,” I said. “You can’t see him because he’s invisible.”

“Nice to meet you.”

“Likewise,” said Millard.

I went over to my father and knelt down beside his chair. His head bobbed slightly. “I’m going away, Dad. You might not see me for a while.”

“Oh, yeah? Where are you going?”

“On a trip.”

“A trip,” he repeated. “When will you be back?”

“I don’t really know.”

He shook his head. “Just like your grandfather.” Millard ran tap water into a glass and brought it to him, and Dad reached out and took it, as though floating glasses weren’t at all unusual. I guess he really thought he was dreaming. “Well, goodnight,” he said and then stood up, steadied himself on the chair, and stumbled back into his bedroom. Stopping at the door, he turned to face me.

“Jake?”

“Yeah, Dad?”

“Be careful, okay?”

I nodded. He closed the door. A moment later I heard him fall into bed.

I sat down and rubbed my face. I didn’t know how to feel.

“Did we help?” Olive asked from her perch on the ceiling.

“I’m not sure,” I said. “I don’t think so. He’ll just wake up later thinking he dreamed all of you.”

“You could write a letter,” Millard suggested. “Tell him anything you like—it’s not as if he’ll be able to follow us.”

“I did write a letter. But it’s not proof.”

“Ah,” he replied. “Yes, I see your problem.”

“Nice problem to have,” said Olive. “Wish my mum and dad had loved me enough to worry when I left home.”

Emma reached up and squeezed her hand. Then she said, “I might have proof.”

She pulled a small wallet from the waistband of her dress and took out a snapshot. She handed it to me. It was a picture of her and my grandfather when my grandfather was young. All her attention was focused on him, but he seemed elsewhere. It was sad and beautiful and encapsulated what little I knew about their relationship.
