In a futuristic world, kids play with a special game that allows them to be transported to any place back in time, but when the creators of the JumpMan games decide to rig the machines against their users, Theo finds himself in a real bad place when he stumbles upon his best friend asking his girl out on a date. Reprint.

The Adventure Continues.... Rule One of TimeJumping was broken, but luckily disaster has been averted (at least for now), and Jules, Gen, and Theo are back. Their first adventure had them whisking through Time, talking to coats, and just managing to save Theo's life—but that was just a warm-up. In the second chapter of the mind-bending TimeJumpers series, Jules and Gen (finally) go on a date, Theo turns out to be the biggest celebrity anyone in the year Fourteen Billion and Seventy-Three has ever seen, and we meet a peculiar and very irritating old man who has the strange idea that the entire history of the world is about to be overturned—and somehow Jules and Gen are involved. And that's just the beginning. There are sinister forces at work, and Rule One is not just going to be broken, it's going to be smashed apart.

The Adventure Ends. In the third millennium, Jules is suddenly very popular, for reasons he doesn't really understand. He should be happy, but all he can think about is Theo. Are Jules and Gen ever going to see him again? Meanwhile, in the fifteenth billennium, Quincy Carter One has disappeared after the world witnessed his aborted attempt to undermine the entire structure of Time. Not only that, TimeJumping has been all but outlawed on the Two Planets. And Theo can't stop worrying about Jules and Gen—and what Quincy may be planning, wherever (or whenever) he is. It's the thrilling conclusion of the TimeJumpers trilogy, and no one knows what's going to happen next. Or before. But that's what happens when you start fooling around with time.
