The 25-year-old from Harrisonburg lost his left leg to a cancerous tumour in his femur when he was nine and took up skiing eight years later.

He competed in the slalom and giant slalom in Turin and, although he did not medal, has turned his memoirs into a book published last month.

Called Just Don't Fall: How I Grew Up, Conquered Illness, and Made it Down the Mountain, it was released last month it has already sold several thousand copies.

Sundquist said: "Just I'm kind of always looking for new ways to share my story, like YouTube videos, writing blogs, the book was sort of a natural progression for me.

"Obviously my story is about overcoming bad things in life.

"And I think that's something everyone can relate to."

Sundquist was formerly the national spokesman for the Combined Federal Campaign, an effort that raises over $300 million dollars a year for charities.

He has been featured on the back of Doritos bags nationwide for being the founder of LessThanFour.org, the world's largest social networking website for amputees.

As a writer, he has been published in The Washington Post, Daily Guideposts, and Current, Newsweek's college magazine.

He was a columnist for the Richmond Times Dispatch for two years, and in 2003 he co-authored the teen devotional book Forty Voices: Stories of Hope from Our Generation.

Competing in Turin in 2006 was the pinnacle of Sundquist's career, however.

He said:  "You know some people go to the Olympics [sic] with this 'I'm trying to win a medal' kind of attitude, and I'm kind of like, 'Whoa, I can't believe I got here.'

"So it was pretty special."
