JOANNE Lees' book about the chilling murder of her boyfriend in the Australian outback has sparked a bidding war.
British newspapers are believed to be offering figures up to £250,000 to publish extracts from the book, entitled No Turning Back.
The book is the story of the murder of Hepworth man Peter Falconio and the attempted abduction of Joanne, from Almondbury, on a lonely outback road nearly five years ago.
Peter's body has never been found.
Australian drifter Bradley John Murdoch was convicted of Mr Falconio's murder in December last year.
Ms Lees is still writing the book from a rented home on Sydney's North Shore and has explained her motivation for doing so in publisher Hachette's newsletter.
She said: "I have written this book myself and it has been painful.
"This has been a different kind of journey. It has been very emotional and, at times, lonely."
Joanne said she had decided to write the book to give her own version of events.
She added: "I didn't particularly want to share my personal and private life. It got to the stage that I felt it necessary to reclaim my history from the storytellers.
"I want to distinguish facts from myths, I want people to read the truth, to find out who I am, and to judge for themselves.
"This isn't just a book about a crime and a trial.
"I am giving the reader an insight into my life during those years and a chance to share my story."
Joanne said she had spoken to Peter's parents, Joan and Luciano, who gave her their full support.
Joanne added: "I have relived the happy times Pete and I shared. Looking back through my travel diaries and going through photos we took together brought back some wonderful memories.
"For me there is no turning back. What happened to me and Pete can't be changed.
"By telling my story and revealing myself I hope to satisfy those curious about who I am so I can move forward and live my life with my head held high.
"I am not a victim. I am a fighter."
The book - the fifth to be published on the murder - will be released in October, two weeks after an appeal hearing by Murdoch.
