CNN Heroes: Championing children

Magdalena, Colombia (CNN) - To the unaccustomed eye, a man toting 120 books while riding a stubborn donkey would seem nothing short of a circus spectacle. But for hundreds of children in the rural villages of Colombia, Luis Soriano is far from a clown. He is a man with a mission to save rural children from illiteracy.

"There was a time when many people thought that I was going crazy," said Soriano, a native of La Gloria, Colombia. "They'd yell, 'Carnival season is over.' ... Now I've overcome that."

Soriano, 38, is a primary school teacher who spends his free time operating a "biblioburro," a mobile library on donkeys that offers reading education for hundreds of children living in what he describes as "abandoned regions" in the Colombian state of Magdalena. FULL STORY
