"When everything goes without a hitch, where's the challenge, the opportunity to find out what you're made of?" Shania Twain writes on the back cover of her autobiography, 'From This Moment On.'

It's the inspiring story of the humble and tragic beginnings of the woman who went on to become the most successful solo female artist in country music history, and the rollercoaster ride her life has been in the wake of success. Shania reveals secrets even her biggest fans haven't heard in this candid memoir, which can be yours for free! The music icon has teamed up with The Boot to give away 10 copies of her book, along with one grand prize: an autographed acoustic guitar (courtesy of the Music Zoo), an iPad with a digital download of her 'Greatest Hits' album and a copy of 'From This Moment On.'

Shania spares no details in 'From This Moment On,' taking the reader on a journey that starts with her tumultuous childhood, as she weathered abuse at the hands of her stepfather, who was later killed along with Shania's mother in a car crash, leaving her to raise her four siblings by herself. The book chronicles her record-breaking rise to stardom and the man who helped her get there, Robert 'Mutt' Lange, the same man who later broke her heart by cheating with her close friend. But matters of the heart take a happy turn as the novel progresses, as Shania reveals the incredible love story that evolved in the wake of heartache and ended with a walk down the aisle with the true love of her life.

"I am actually grateful for what I've gone through and wouldn't change a thing," Shania writes, "although I admit I wouldn't want to live it over again, either. Once was enough."
