Emma - I know it sounds crazy. You (and Mum!) will be wondering where I've been disappearing to, and when I'll be back.

That's why I'm leaving you all this evidence - in case something happens and I don't come back.

Look at everything in my book. Call the phone numbers. Check out the websites. But, you can't tell anybody about it, unless you want to end up in over your head, like me.

But don't worry, I'll be ok (I think). Hey, maybe this is the beginning of a new life for me.

For sure it's the end of the old one. Call me. Love, Cathy. This book reaches beyond the written word to interact with teenage girls in ways they are quite familiar with in other areas of their lives.

From instant-messaging to text-messaging, from surfing the web to having their own sites, the age-old story of 'boy dumps girl and girl wins boy back' is lifted from the page to our three-dimensional, 21st-century world.
