Pro surfer Bethany Hamilton -- who lost her left arm in a horrifying shark attack in 2003 -- has found yet another way to be an inspiration to the world ... she's authored a new children's book aimed to help kids get past their fears!
The athlete's new work, fittingly called "Surfing Past Fear," dropped earlier this month -- and it's all about an otter named Olivia who faces her fears after she breaks her arm while surfing.
Olivia gets help from her friends Mobi -- a one-armed bear -- and a flamingo named Abby -- and Hamilton says the whole point of the book is to teach kids how to overcome adversity.
