Books by James Valentine

The year is fifteen billion and seventy-three and Theo - teenager, TimeJumper, legend - is the biggest celebrity on the Two Planets. Theo knows there's only one rule when you TimeJump: Don't Touch Anything. They have no idea they're about to TimeJump three thousand years into the future, become invisible, spy on Theo, and try to save the world.

Theodore Pine Four has hair that constantly changes colour, a coat that talks to him and a defective Jumpman Pro! Jumpman is the hilarious account of Theo's time in Mil 3 (which he is VERY unimpressed by) and of Jules and Gen's heroic efforts to rescue him and return him to his own time.
