By Alex Greig PUBLISHED: 17:36 EST, 28 February 2014 | UPDATED: 17:41 EST, 28 February 2014 In little more than a year, one small boy has raised more than three-quarters of a million dollars to help his sick best friend by selling copies of a book he wrote himself. Now well on his way to the ambitious goal of $1 million, Dylan Siegal, a seven-year-old from Los Angeles, is selling his book 'Chocolate Bar' to raise funds for Jonah Pournazarian, eight, his best friend who suffers from a rare condition called glycogen storage disease type 1B.
