One day one of the Chronivac makers visited a middle school. He deposited the device into the first unlocked locker he could find, which belonged to a boy named Henry Evans.
Later that day, Henry went to his locker to retrieve some items for his next class, and saw the small device inside. It looked like a phone, which he'd never had before, so he was thrilled. He took it to class with him, hoping to have some free time to check it out.
Unfortunately, Henry had to wait til the end of the day, his study hall. There were a few others in there with him: his best friend, Jack Rivers; twin seventh graders Peter and Jenna Linder; and eighth graders Ben Walker and Alice Reed. The twins always fought and Ben was always flirting with Alice, but it never worked because she only liked athletes.
