Since publishing the first book in the wildly successful Divergent series at the age of 22, Veronica Roth has been one of the most popular authors of teen dystopian fiction. Roth rounded out the Divergent trilogy with Insurgent and Allegiant; each book in the series has been adapted into a movie of the same name. Her fourth novel, Carve the Mark, is a dystopian tale of a planet ruled by violence and vengeance.
