The first and only rule of time travel in the year fifteen billion and seventy-three is simple enough: DON'T TOUCH ANYTHING. Theodore Pine Four is perfectly willing to follow this rule when he wins a contest for the latest TimeMaster JumpMan. If all goes according to plan, this new model should send him -- as an invisible onlooker -- to an exciting time and place for a fiv ...more

"Jumpman, Rule 1 don't touch anything" by James Valentine is very creative and funny. I really like the style of the book because it's really simple yet complicated at the same time. One of the main characters, Jules, he is not confident at first so the character development at the end really wasn't expected. Jules was my favorite character because he's very funny, he is brave when his life is in danger, and he admits when he is excluded and not needed. Gen , who is another character in the nove ...more

It's cheesy, it's lame, it's predictable, but the characters are so enjoyable. It doesn't do anything new, it rehashes all of the themes that have been done a million times before, but it does it in a way that's so delightfully cheesy that I really couldn't help but smile. Not a must read but definitely a worthwhile read.

The main characters of the book are Jules, Theodore, and Gen. The novel is about a certain time traveler that has jumped to Mil3 and is visible to everyone one that's around him which isn't supposed to be happening. So she/he tries to jump back home and they can't so they need help from their newly made friends in order to jump back. I gave the book a 4 star rating (clearly). This is mainly because I was watching TV after every chapter I read because the book was so confusing at times. Time trav ...more

Jules fights with his brain. Well, he's always talking to his brain, probably too much, but sometimes, yeah, the duke it out. Like now - while he's standing outside Gen's door, his dad downstairs with her parents getting ready for a barbeque dinner. After two years, he came to dinner again like old times, before he moved away with his mom. Now it was Dad's turn to have him for a bit, and well, Gen was not the girl he remembered...not the friend he remembered. She made him, well, a bit crazy. So ...more

In the early Fifteenth Billenium, everyone has the ability to "jump" to any time in history they please, but with one rule: don't touch anything.

When Theodore Pine Four wins a worldwide contest, he is thrilled! He is the first person ever to try the new JumpMan and jump to the winners' secret location. When Theodore jumps with the new JumpMan, he leaves the Fifteenth Billenium...and never returns!

Over to do his homework with his crush, Gen, Jules Santori
Ms. Patterson
Just when Jules finally gets up his nerve to ask Gen on a date, Theo pops in to their live. He literally pops into Gen's room out of nowhere. He's a time-jumper from the future and is mistakenly sent to Mil 3, which is our present day. Apparently in the future, time-travel is common place, but the jumpers are invisible to the people of the current time. Only, something has malfunctioned in Theo's jump and he's visible. Jules and Gen work with Theo to try and return him to his own time.

Okay, not

The book opens in a suburban town where a boy named Jules is trying to ask out a girl named Gen. He has dinner at her house because they are old family friends, and afterward they do homework in Gen's room. All is well until a strange boy appears out of the air, and lands in the bedroom. He looked as if he was from the future, and he leaves Gen and Jules speechless. In Jumpman by James Valentine, there are interesting characters, greatly illustrated views on time travel, and a beginning that is ...more

A weird boy suddenly appeared in Jules and Gen's room. Turns out he is from the future and he time traveled here. But the time jumper malfunctions and Theodore, the kid from the future is stuck on earth. He gets really sick and Jules and Gen had to travel to all sorts of places to get the jumpman fixed. After, they finally fix it and Theodore goes back to the future.

I picked this book up because I read the back and I thought that it would be cool if someone came from the future and lived on eart

I thought this book had a really fun concept and I would like to see more done with it. Much of the book is spent with characters talking in the bedroom and i would have liked to see more of Theo from the future interacting with the present earth and them getting into adventures across time. I think because it's a trilogy he might do more in the next books. The foundation for time jumping was layed very well. I also think Theo seems very fun and futuristic with his personality, hair, and compute ...more

I really did enjoy this book. I really like books about the future - as the author can just sp0ill out all their ideas into the book as we dont know what the future will be - just like this author did. The clever invention to travel in time
I have to say though there wasnt any real danger in the book - there was nothing to keep you latched on to see what happened next - no-one was ever ina ny real danger. I would recommend this book to anyone of any age, but I would say 11-14 is the best audienc

i'll just have to rate it 2 of 5. The plot is quite disturbing and uncanny. It would be better to read the whole series in order to fully understand the story. Though some may find it interesting (the fictional way) and has funny spots but well, every reader has different expectations. I thought the book will showcase the plot but i was wrong. Somehow, solid characters like Theo are quite intriguing. I recommend to read first book 1 of time jumpers. :D

Really fun read. What I both liked (and didn't) was the time that Theo jumped to was never explained in out terms. The book also seemed to be a cautionary tale (environmental problems can cause horrible things in the future).
