A little boy is touching hearts all the over the world. He wanted to call attention to his best friend's rare and potentially deadly disease so he wrote a book that's seeing incredible success.
Jonah Pournazarian, 8, suffers from glycogen storage disease, a disorder that makes his liver able to store sugar but not release it. And when his friend 6-year-old Dylan Siegel found out that Jonah's doctor was almost out of funding for research about the illness, he decided to take action.
Dylan wrote the book, "Chocolate Bar," and it may very well save the lab where his friend's disease is being studied.
Dylan has raised more than $750,000 by selling the $20 book in all 50 states and 42 counties. All the proceeds go Jonah's doctor for lab funding.
