The novel by Anne Tyler, entitled Dinner at the Homesick Restaurant, is written in three sections.
The novel is about the life of Pearl Tull (and her impending death), and the family she has "created" with her children. Part I is written from Pearl's perspective, with memories strung together, attaching themselves to other memories—one after the other.
Part II gives her children (Cody, Jenny, and Ezra) the opportunity to tell the story from their own perspectives.
Part III is the account of Pearl's death from Cody Tull's perspective. (He is Pearl's oldest son.)
Look to the following quote for a metaphor. (The part about the piano scales is simply wonderful imagery.) Metaphors can be general in nature, when any two dissimilar things with similar characteristics are compared, and like or as are NOT used. Besides being metaphors, some forms of imagery may have other "labels" as well.
This is a diary entry that Ezra reads to his mother.
"The Bedloe girls' piano scales were floating out her window," he read, "and a bottle fly was buzzing in the grass, and I saw that I was kneeling on such a beautiful green little planet..." (from Part II).
The metaphor comes from the phrase, "kneeling on such a beautiful green little planet," where the patch of grass she is kneeling on is compared to a beautiful green planet. (It infers that the grass she kneels on is like a green plant, but the word, "like" is NOT used.)
