If you were an animal, what would you be? This is the question Blaise, Ash and Dinah unexpectedly stumble upon during the summer holidays when they enter a strange internet café and a mysterious woman asks them to take an online test to discover their inner beast. They are happy to oblige. Online tests are always fun and this one comes with its own special perks. But what they don’t realise is that not far away, in the heart of London, a mad professor is watching them. Professor Polgas is preparing something; something that will change them forever; something that will have them on the run for their very lives.
