One of the key themes in "The Hunger Games" series is the abuse of power and the consequences of a society where power is concentrated in the hands of a few. The Capitol exerts its control over the districts through violence, oppression, and manipulation, creating a stark divide between the wealthy, powerful Capitol and the impoverished, oppressed districts. This theme is further explored through the characters' struggles against the oppressive system and their efforts to resist and overthrow it. Other themes in the book include survival, sacrifice, rebellion, and the impact of media and entertainment on society.
