Sandra Swain loves to write children's books as an opportunity for children to learn life lessons.  The lesson she offers in "How Willie the Wombat Won the Race" is that if you believe you can, you can.  She modeled the situation after the story of Roger Bannister's 4 minute mile.  No one believed it could be done until Roger Bannister did it, then one by one others achieved the same mile marker.  

This and other books are available at Amazon, Target, and Walmart online.  She's also very active in social media with 2,000,000 Facebook users.  U.S reviews of her books have been good and she was a finalist in the Eric Hoffer Book Awards.  She has just started a Good Reads campaign.  This is a good book for schools to use in group discussions.
