What research topics could you use with your current book?

[Darcy]

For example, if I were reading the Hunger Games, I might research these topics:

--Roman Gladiators: How were the gladiators picked?
--Dystopian literature: what other books and films are there? How do they compare?
--Child soldiers (The tributes essentially are children dying for their country)
--What modern-day rebellions are going on?
--
