It is easy to see why teens love this book. It's a fast-paced suspenseful adventure, but it's also completely overwrought with all the angsty teen emotions of rebelliousness, persecution, despair, and homesickness. Katniss can switch between hating her mother and loving her mother with a speed and intensity that only a teenage girl can achieve.
Being hunted in an arena aside, Katniss has some major issues. Her father's death and her mother's psychological instability have forced her into self-reliance far too early and now she is incapable of achieving real intimacy with anyone unless she is acting as a self-sacrificing protector for them. You have to pity Peeta and Gale both for falling for this emotionally unavailable mess.
Don't get me wrong, Katniss is strong, capable, independent, and intelligent. She is a far better role model for young girls than that other fictional character with the thing for vampires and werewolves.
