Oscar is not looking forward to Grandad coming to look after him at the weekend - it means he`ll have to play endless rounds of chess or Monopoly, instead of war games on his computer. But when he finds Dad`s ancient laptop in the study, he can`t resist logging on to something called Project X - and all too soon Oscar creates a real live warrior, who is programmed to obey his every command. However Monstroso`s wires are more than a little crossed, and Oscar finds himself in all sorts of fighting and monsters abound in Charlie`s Higson`s highly entertaining story for younger readers.
