"She said I should ask my guides to write so I gave it a try. She said you had to do it last thing at night or first thing in the morning, and I sat down to write and soon I had one-and-a-half pages.
"You know when you do something you really love, you have that feeling?"
Her autobiography tracks her life growing up in Ireland to her life in Rotorua today.
She said she told stories to people she massaged and thought if she wrote an autobiography her tales would reach a wider audience.
"I was brought up in an emotionally challenging, non-nurturing environment.
"Perhaps I can reach a greater audience, and show the vulnerable side.
"It's a risk ... but life goes on, the sun will rise."
She said she hoped other people would be able to take something from her autobiography.
"It's my voice; this is my life through my eyes. It was an amazing sense of relief getting it down and out of my system. I hope it will help other people."
Siobhan Foster's double book launch will be held on Thursday at 6pm at the Rotorua Library.
