In "Mockingbird" by Kathryn Erskine, similes are used to compare things in the story to other objects or ideas using "like" or "as." For example, one simile in the novel could be "Asperger's syndrome is like a puzzle with missing pieces." These comparisons help to create vivid images and convey complex emotions in the story.
