'A stopwatch has sixty thin black lines, each marking off the seconds in a minute. But in Tom's grandfather's stopwatch, they are also gateways to different worlds. And Tom just cant wait to 'borrow' it. He soon finds himself sucked into a very different world indeed - a world of monsters and warfare. He is not on Earth anymore. In fact, he doesn't know where he is!' (Publisher's blurb)
