In "The Lightning Thief" by Rick Riordan, a vivid description of a character's appearance highlights her unique features. The author uses a striking metaphor to convey the brightness of her freckles, comparing them to the bold hue of liquid Cheetos. This imagery not only captures the reader's attention but also adds a whimsical touch to the character’s portrayal.

The use of unusual comparisons in literature can create memorable impressions of characters, as seen in this example. By likening her freckles to a common snack, Riordan gives a playful and vivid image that engages the reader's imagination, making the character stand out in the narrative.
