One book that I think was similar to Divergent is The Hunger Games. The reason that I think this is because first of all, they are both set in futuristic or even imaginary settings where people live fearful lives. Also, both of the books have a main character that is a brave female going against leaders/government. They (Tris and Katniss) also both make a huge impact on their nation's future. Lastly, I noticed that both books have the people isolated or separated from each other. In Divergent, there are five different factions. In The Hunger Games; there are twelve different districts.
Prompt - What are the two most important ideas in what you've been reading?
There are many, many important ideas/themes in Divergent; such as: identity, fear, family, friends, society, class, power, competition, choices, secrets, etc. Although, I think the main two key ideas were Choices and Power. The idea of choices was shown in the beginning of the book when Tris (the main character) had to choose what faction she wanted to be in when she turned sixteen. Her choice would impact her life and the lives of her family and people around her.
The theme of power was shown all throughout the book. For example, in one of Tris's fear simulations; she didn't have to have power as in physical strength, but she had to be mentally powerful to come back to reality. Also, she had the power to do things such as the power to save people from Abnegation (her original faction) from the mind controlled Dauntless soldiers which was caused by Erudite. Finally, I think that those two themes were the most important in this book.
