The Iraq war veteran and actor began writing his tome before the dancing competition began, but now that the show is over, Martinez can get back to work.

His rep tells the NY Post that the book will be "full of things people don't know." Although the book has not yet found a publisher, the interest has grown since his DWTS win, according to the site.

Since 2003, Martinez has undergone 33 surgeries after his Humvee triggered a land mine in Iraq and he suffered severe burns over most of his body.

Martinez will be the Grand Marshal for the Pasadena Tournament of Roses Parade taking place on January 2.
