<p>Since publishing the first book in the wildly successful <a href="http://www.barnesandnoble.com/b/divergent/_/N-1p7a">Divergent series</a> 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 <i>Insurgent</i> and <i>Allegiant</i>; each book in the series has been adapted into a movie of the same name. Her fourth novel, <i>Carve the Mark</i>, is a dystopian tale of a planet ruled by violence and vengeance.</p>
