Leading on from the saga that began in Cathy’s Book and Cathy’s Key, this final installment (sniff) sees Cathy’s already dramatic life get even more exciting. As well as becoming totally involved with Cathy and her antics, the book draws you in even further by including phone numbers you can ring to find out secret messages (you can also check them out online if you want to save your mobile credit). The pages are littered with Cathy’s cool illustrations and doodles, plus you get a fab pull out poster. As if all this wasn’t enough, there’s a cute silver ring tucked into the front page – you can’t get more interactive than that!
