Veronica Roth hit it big with her debut trilogy, “Divergent,” which has been optioned for the movies. She wrote the first book in the series instead of doing her college homework. “Insurgent” is the second book in the series, and the final volume is “Allegiant” (Katherine Tegen Books/HarperCollins). The series is set in a dystopian Chicago, the city where Roth lives. In the “Divergent” world, society is divided into five factions, each dedicated to the cultivation of a particular virtue.
