Although Suzanne Collins' Catching Fire did not necessarily need specific words to create interest in the sequel to The Hunger Games, it always helps when a novel's language creates vivid images in the mind of the reader. Words create characters.
On the opening page of the novel, Katniss Everdeen tells of her desire to completely forget the Games. She is hunting in the woods and knows the reporters will be at her house soon. Muscles aching, Katniss forces herself up. If one is familiar with Katniss' character, he or she knows about Katniss' tenacity.
Some of the specific words which Collins' uses to create interesting characters for the reader are as follows.
Katniss: "I have killed," "mourn my old life," "rich, famous, and hated," "formal"
Gale: "Alive in the woods," "a whiz," "skilled trapper," "handsome"
Peeta Mellark: "madly in love"
Haymitch: "surly, violent, and drunk," "guttural animal sounds"
President Snow: "snakelike," "sadistic"
