New York to Paris. He did it all by himself, and it took him something like thirty-three hours—he stayed awake the whole time. He was the first one to fly that route. People had tried it before, but they always died.”
    Jonah knew he was supposed to be impressed. But he just couldn’t care, when Katherine was missing.
    â€œDo you know about Lindbergh’s son?” Angela asked. “It was like, I don’t know, five or six years after Lindbergh’s famous flight. His son was kidnapped.”
    â€œI know, I know,” Jonah said glumly. “By Gary and Hodge. Just like all the other missing children from history.”
    Angela wrinkled up her nose as if she was trying hard to remember something.
    â€œIt’s funny,” she said. “My memory of this is so fuzzy. And . . . it seems to be getting fuzzier the more I thinkabout it. But Lindbergh’s baby was kidnapped in real, original time too. Even before Gary and Hodge got involved. The kidnapper was executed, but—did they ever find the baby’s body? Or did they find a body that they thought was the Lindbergh baby, but . . .”
    Her voice trailed off.
    â€œIt was a baby boy , right?” Jonah asked. “Not a baby girl, where Charles Lindbergh might think that if he kidnapped Katherine . . .”
    He was working on a theory: What if Gary and Hodge had told Charles Lindbergh that Katherine was really his child? What if that was the reason Lindbergh had snatched her?
    It didn’t make sense. And anyhow Angela was shaking her head.
    â€œThe Lindbergh baby who got kidnapped was definitely a boy,” she said. “No doubt about it.”
    Jonah slumped in his seat. He knew he should be thinking of other questions to ask about Charles Lindbergh, but none of it seemed to matter.
    â€œI hadn’t thought about all those historic pilots in years,” kid Angela said. “Did I ever tell you—I started working at the airport in the first place because I thought that was how I’d eventually get to be a pilot? I was too poor to pay for flying lessons, and I didn’t want to go into the militaryto learn. I used to idolize Charles Lindbergh. Well, before I found out some of the bad things about him.”
    â€œYou mean, like the fact that he went more than forty years into the future to kidnap Katherine?” Jonah muttered.
    Before Angela had a chance to answer, JB let out a whoop from across the room.
    â€œIt’s up!” he screamed. “I got the monitors to work! Come see!”
    Jonah hurled himself out of the car and raced toward the wall full of monitors. He had a head start, but Angela passed him after three steps.
    Even as he approached the wall, Jonah could tell that JB had set the monitors to cycle through the same moment in time in several different locations. On one screen there was Chip, standing in the foyer of his house, right by the front door. And then, a second later, he vanished.
    On the next screen there was a dark-haired girl— hey, isn’t that Ming Reynolds? Jonah thought.
    She was another missing child from history, but Jonah hadn’t seen her since the last time he’d been in this cave. On the screen Ming was sitting at a table dropping blueberries into a bowl of yogurt.
    And then a moment later, Ming vanished, just like Chip. The table and the bowl and the yogurt and blueberries were still there, but not Ming.
    All across the monitors, kids were vanishing.
    There was Brendan . . . and now he was gone.
    Emily . . . gone.
    Antonio . . . gone.
    Gavin . . . gone.
    Daniella . . . gone.
    Andrea . . . gone.
    Andrea! Jonah felt like screaming. Andrea!
    In front of him, several yards back from the wall full of monitors, Angela stopped short.
    â€œWho’s left?” she asked, her voice breaking with anguish. “Of all the missing children from history . . . how
