Wingo the Superhero [EPUB ebook] 

Wingo was a draft cross horse who was the best horse ever. He was such a character. If Wingo could talk, he would have told stories about the horses at the barn, the workers, and the riders. He knew where all the horses should be at all times. He was the big brother of all the horses. He knew as soon as I pulled up in my car to the barn, he would come galloping to the fence and give me a huge neigh.

I decided to write a book about this gentle giant to give children a view of how horses can be best friends with their owners and riders.
