This book is set in a futuristic Chicago, after a terrible war that destroyed the world. The city is split into 5 factions: Dauntless, the brave, Erudite, the intelligent, Candor, the honest, Amity, the peaceful, and Abnegation, the selfless. At age 16, everyone will take a test to determine which faction best suits them, but when Beatrice (Tris) Prior, from Abnegation, takes the test, she gets 3 different results. She is Divergent. She must choose between her family and what she wants, and when she does choose, she finds out about a plan to eliminate all the Divergents. This book is awesome, and I recommend it to anybody who likes post apocalyptic books, dystopian fiction, or The Hunger Games.
