While it contains themes and elements that appeal to adults, the protagonist, Katniss Everdeen, is 16 years old at the start of the series, and the story is told from her perspective. The book also deals with issues and challenges that are typically explored in young adult fiction, such as coming of age, navigating difficult relationships, and facing life-or-death situations.
However, the series also explores more mature themes like political corruption, social injustice, and the horrors of war, making it engaging for readers of all ages.
