In the book, Shania shares her "challenging and sometimes shockingly painful upbringing in rural Ontario," the tragic death of her mother and stepfather, her rise to fame and the recent struggles in her personal life.
"There have been moments in my life I was concerned by the reality that tomorrow would never come," she explains. "Recently I experienced one of those moments to an intensity that brought on a sudden urgency to document my life before I ran out of time, before I had the opportunity to share an honest and complete account of my life, in my own words."
The book is likely to recount some of the happier times in the country phenomenon's life, as well. She married Frédéric Thiébaud in Puerto Rico on New Year's Day 2011, after becoming romantically involved in 2009.
Shania posted a letter to her fans on her website in December to share news of the engagement, writing, "The support of others has helped me to move forward less fearful of change, allowing me to embrace the beauty of life today and remain more open to whatever it brings tomorrow ... In the last two-and-a-half years of adjusting to life after separation and divorce, I needed to lean on others more often than I was accustomed to ... I'm in love! Frédéric Nicolas Thiébaud has been a true gift to me as a compassionate, understanding friend and over time, an amazing love has blossomed from this precious friendship."
The book is being published by Atria Books, an imprint of Simon and Schuster.
Also in the pipeline for Shania is her reality show 'Why Not?' which is scheduled to premiere on Oprah Winfrey's OWN Network in April.
