It''s the summer holidays and Millie is bored stiff.

Every week, she has to clean windows with her dad at a nearby laboratory. But she''s sure something weird is going on inside… Then, one day, a cat comes hurtling through the lobby towards her… and asks her for help. And Max needs a lot of help. He''s trying to escape, he wants to know who kidnapped him, and why - who on earth would want to make cats that can talk? And he needs Millie to help him rescue the friends he''s left behind before it''s too late…

International animal-smuggling, illicit computer-hacking, break-neck chases and a fast-talking cat. Just your ordinary summer holidays...
