Martyn Williams: The Magnificent Seven. The Autobiography by Martyn Williams with Simon Thomas, published by John Blake will be available in the Cardiff Blues shop shortly priced at £17.99.
"I really enjoyed doing the book, and yes, the main thing is that it can be something my kids can look back to in the future," said Martyn.
"I have tried to be as honest as I possibly can be and people should remember that the book is simply me calling things the way I saw them.
"Others may well have a different view on events that I was involved in and that's fair enough because we all see things differently."
"My intention would never to be sensationalist for the sake of it."
Martyn has decided to donate most of the money made from the book to Cancer Care Cymru, with the battle against something that affects so many people very prominent in his thinking.
