Cue the theme music to Jaws ... only 2 days to go before I squeeze myself into a wetsuit and - gulp - dive with sharks.
I've been invited by Blue Planet Aquarium in Cheshire to take up the challenge that features in Three Little Birds and is the one that Charlie fears most. Initially, I wasn't keen because, like the main character in the book, I am terrified of sharks. However, it's all for a good cause.
Proceeds from all book sales and goody bags will go to the Back-Up Trust that helps to transform people's lives after they have suffered spinal cord injury. They are a little-known charity and they do extraordinary good work.
Why not come up to the aquarium where you can take a tour and admire the creatures of the sea then laugh at my attempts to dive? I'll also be selling and signing copies of my book and offering you fabulous goody bags in return for small donations to the charity.
You can also donate by sponsoring me to do the dive on my JustGiving Page. Every pound counts so please help me reach my target.
