YouTube celebrities are getting more than deals for their own web series, TV shows, and movies: the trend of YouTube authors is growing. Although some have questioned the vloggers’ capabilities as writers, recent books published by YouTube stars have seen unexpected successes. Grace’s Heibig’s Grace’s Guide: The Art of Pretending to be a Grown-Upeven became a New York Times bestseller. It was just announced that four top YouTubers will even host their own session at BookCon, the largest literary event for authors, publishers, and readers. Justine Ezarik, Shane Dawson, Connor Franta and Joey Graceffa will speak about their new literary efforts with Keywords Press, an Atria Books imprint specially created for online video stars and their fans.
