All of her life, Becky Siame has struggled with her weight. She started doing a series of cartoons about her experiences, with a caricature of herself as the central character. But publishers turned it down. Then she decided she'd write a novel, "The Lighter Side of Large" and publishers turned that down too. So she put it online as a eBook. Last week, during a three-day free download offer, more than 33,000 readers downloaded the book.
