I have just finished one of the best books I've ever read - JumpMan Rule #1. Honestly, I cannot say enough about this fantastic book. Theo is a teenager from the year 15,000,073, where TimeJumping (time traveling) is not only possible, but the most popular form of entertainment for the people of the future. Of course, to avoid messing up all of history, everyone who TimeJumps is rendered invisible, and has to follow one rule: DON'T TOUCH ANYTHING. Theo has just won the opportunity to be the first kid to try out the new JumpMan, but instead of going to some cool place in history, he lands in a regular bedroom in the year 2004, just as one kid from our time, Jules, is about to ask his friend Gen out on a date. And to top things off, Theo's JumpMan won't send him back to where he came from.
While this sounds like a typical sci-fi/adventure novel, it is so much more than that. It presents enough awesome visions of future technology for science fiction fans, but the author also concentrates on what really matters in the book - the characters of Jules, Gen, and Theo. The level of detail the author has in his world is amazing. For instance, Theo's futuristic Coat, which can change color, length, and style, while simultaneously measuring the temperature, translating foreign languages, and monitoring the fat content of the food you're eating. But then there is the story of Jules just trying to be a regular teenager, which is hard enough without time travelers dropping in when you're trying to ask a girl out on a date.
This is just a really great book, and I can't wait for the other books in the series. I highly recommend it if you are looking for a good science fiction book, or just a good book.
