Welford, Ross: Time Travelling with a Hamster

My dad died twice. Once when he was thirty nine and again four years later when he was twelve.The first time had nothing to do with me. The second time definitely did, but I would never even have been there if it hadn't been for his 'time machine'...When Al Chaudhury discovers his late dad's time machine, he finds that going back to the 1980s requires daring and imagination. It also requires lies, theft, burglary, and setting his school on fire. All without losing his pet hamster, Alan Shearer.
