The Bay Area is home to Raina Telgemeier, a best-selling author and illustrator behind the books "Smile," "Drama," "Sisters" and "Ghosts." KTVU's Gasia Mikaelian sat down with the author who tells the story of when she fell and knocked out her two front teeth. Telgemeier said she drew on those experiences and emotions for her first book, the graphic memoir titled "Smile." That book spent more than four years on the New York Times bestseller list.
