Publisher's Synopsis
'Outside my window the police are chasing a Triceratops that has strayed onto our street. In the next room Dad is going on about how extra-terrestrials are taking all the best jobs, and my brother is pestering Mum for help training his pet Tasmanian tiger to roll over. There's no way around it. The world isn't what it was when I woke up yestereday - and it's all my fault.' - So begins the tale of 12 and 3/4 year old Chelsea McAllister in this science-fiction adventure that not only shows how important it is to pay attention in Science class, but also why it is never a good idea to press random buttons in a time machine.
