A mother has penned her first novel in memory of her 15-year-old daughter who was found dead at her Westbury home nine years ago.

Two weeks before she died, Francis Scane asked her mum Carole Scane to write a book for her.

It has taken Carole four and a half years to produce a fantasy fiction novel entitled Light in Darkness.

Mrs Scane said: "I was helping Francis with her GCSE English homework two weeks before she died and she said to me 'Mum, write me a book', so I have.

"I have dedicated my book to my beautiful daughter to fulfil a promise I made to her two weeks before she gained her angel wings."

The book is the first the 62-year-old mother-of-eight has ever written and is the first part of The Celestine trilogy.

The general themes include angels and demons, the battle between the forces of light and darkness, and corruption within the church.

The heroine is a girl called Evangeline, who is born within a forbidden forest, and grows up to become the saviour many have waited for.

Mrs Scane published it at £9.99 in mid-September through Michel Terence Publishing on Amazon and is expecting it to hit retail bookshops within the next few weeks.

"I don't expect to sell millions of copies, it has not been written for that. It was done to fulfil a promise to Francis and no other reason."

On September 11 2010 Mrs Scane found her daughter dead at her home in Railway Close, Westbury.

The Trowbridge schoolgirl was laid to rest at Westbury Cemetery after a moving funeral service at All Saints Church attended by close family and friends.

Moving tributes were made in the packed church by distraught family members, including her parents and older brothers and sisters.

Her father, Barrie Scane said at the funeral: “She was everything that a father could ask for. I was blessed with her for 15 years.”

Andy Packer, the former headteacher at John of Gaunt School in Trowbridge, where Francis was a Year 11 pupil, described her as 'force of nature'.

Mrs Scane, who works part-time as a housekeeper at Center Parcs Longleat Forest, is already working on the second novel, to be called Shattered.

But she admits that, for her, writing is hard work. "When I was a child, I hated school. I had a degree in truancy.

"Writing this book has been a labour of love, blood, sweat and tears. I have been helped by Keith Abbott, the executive director of Michael Terence Publishing.

"This novel has taken me four and a half years to write and it's been a very emotional journey.

"I have only been able to write when the mood takes me, and at one point I put it down for a year and then picked it up again.

"Some of it was written around the anniversary of the date that Francis was buried - September 24."

Now her mother is hoping that Francis' spirit will live on through the novels that she has helped to inspire.
