“I’m here because of him. Here in this situation and here in this town. Because of Jack.” When I didn’t answer, her hands dropped limply to her sides. “Why would any of you keep that a secret?”

“Because we don’t know anything for certain.” I couldn’t answer her truthfully. I didn’t want to give her any information that wasn’t absolute.

“If he isn’t found, and time goes into rewind, it could affect me.”

“If you’re here because of him, yes, you’d be impacted by a rewind.”

“Which means my grandmother would be, too.” I heard the realization dawn in her voice. “Possibly my extended family.”

“Possibly.”

“This throws a whole different perspective on things.” She took a deep breath, and I could feel her mind shifting to accept the truth. “I really am the only option for finding Jack.”

“No. If my dad can re-create the formula needed to time travel, it would provide a really easy fix. Intercepting Jack at a known place in his past would be the fastest way to find him.”

“How’s that working out?” she asked, her eyes steady on mine.

I frowned. “It’s not, exactly.”

“His past,” she mused. “What about his past?”

“If they make the formula work, I’m not sure where they’ll go to find him—”

“I’m not talking about the formula. Jack’s stirred up all this trouble because he wants something changed. He wants a ticket back to his past.” She almost bounced as she asked her next question. “Has anyone ever asked why?”

I sat at our table with my back to the kitchen door. Sophie had been assigned as the lookout for Abi. Even so, Lily stood with an order pad in her hand, leaning against the table instead of sitting down with me. Her apprehension at being caught by her grandmother made me a little afraid. Abi appeared to be the kind of woman you didn’t want to mess with, and I was helping her granddaughter break a huge rule.

I wished I could see enough to keep an eye out for Abi, too.

“We’ve never tried to figure out why he wants the past changed,” I said, continuing our conversation from outside. “Just why Jack didn’t change his past himself, and why he needed Em to do it for him.”

“No one knows the reason?”

“There are a couple of theories. Em thinks maybe there’s some reason he didn’t want to mess with his own time line, but I don’t think Jack cares about breaking rules. Michael thinks it’s because the exotic matter formula was unstable, and Jack couldn’t travel far enough to do what he wanted.”

“I have no theories. Time travel makes my head hurt.” She bit her bottom lip. “How old is Jack?”

“Midthirties.”

“Your dad is in his midforties.” She made a note on the order pad. “And Jack’s known your dad how long?”

“About fifteen or sixteen years. That’s when Jack became Dad’s lab assistant.”

“Fifteen years is a long time,” Lily observed, still writing. “And a lot of memories. Not to mention how hard it would be to keep track of who knew what. Lots of people are involved at the university level. Staff, students, colleagues at other schools.”

“Keep going.”

“I agree with you. I don’t think Jack cares about rules, which makes me think what he wants changed didn’t happen recently. I think it happened way before he came to Ivy Springs. Maybe even before he started college at Bennett.”

“We don’t know where he came from.” I rubbed my temples. “Our friend Dune’s been researching, but we don’t know anything about his background.”

“But someone has to, somewhere.” She leaned one hand on the table and tapped the end of the pen against her lips. “He could erase memories, maybe even find someone to help him erase complete computer databases, but not paper trails. Not every single one. Think about all the things that were on paper twenty-five years ago that are on computers now. Report cards, school records, annuals.”

I gave her a sarcastic smile. “I’m sure Dune’s taken all that into consideration.”

“Don’t condescend to me, Kaleb Ballard.” Lily snapped to attention, standing straight up. “I’m thinking out loud, and you’re supposed to be helping me brainstorm, not making judgments.”

I sat back in my chair and laced my hands around one knee. “Sorry.”

“We’ve established that you’re sorry.” I caught a hint of amusement under the harshness of her words. “I’m only saying, there’s no harm in asking Dune if he’s thought of that angle, and if he has, to ask if he has a plan for how you guys are going to approach it.”

“Lily,” Sophie whispered urgently over the counter. “She’s back.”

“So,” Lily said brightly, pen poised over the order pad with efficiency. “That’s two cheese and tomato paninis, a side order of sweet potato fries, another side order of pasta salad, and two vanilla cream cupcakes? What can I get you to drink with that?”

I stared at her. “A water tower?”

“Coming right up.” She smiled, ripped the paper off the pad, slammed it down on my table, and walked toward the kitchen. She called out something in Spanish as she walked through the swinging door.

I looked down to see what the order ticket said. She’d written down the entire list she’d rattled off to me, with the addition of water tower.

And below that, Twenty-five percent tip included. XOXO, Lily.

Chapter 15

I stared across the quad at the science building, waiting. A pile of red and brown leaves whipped into a tiny little tornado and bounced against the brick foundation.

“Well?” I asked Dune.

“Nothing online,” Dune said. He’d left his laptop at home. Bad sign. “No evidence of his existence.”

In addition to his excellence at research, Dune had the supernatural ability to control the tide and the phases of the moon. I was glad the power to cause multiple natural disasters was contained in one of the most kind and logical people alive.

“I couldn’t find anything in Dad’s office.” I stuck my thumbs in my back pockets. “Paychecks from the Hourglass don’t exactly run through any of the normal government processes.”

Nate kicked at a rock on the ground. “And there’s no one to ask around here, because Jack pulled his Jedi mind tricks on anyone who’d have any decent information.”

Dune turned his entire huge frame to the side and stared at Nate. “Please do not disparage the Force by including it in the same sentence as Jack Landers’s name.”

“You just did,” Nate pointed out, making an “oof” sound when Dune elbowed him.

I knew it had to hurt. Dune had told us he was the smallest of his Samoan brothers, coming in at only 220 pounds and 5 feet 11. Just one of the reasons I tried to stay on Dune’s good side.

I cleared my throat. “So Lily was right. A paper trail is the best chance we have to find out what Jack wants. And since he used to work here …” Dad had just started a three-hour staff enrichment, along with the rest of the physics department, so we were free and clear to get in and dig around. We’d stood behind a couple of trees and watched them trek from the science building to the administration office.
