Prose Poetry
Go into the young adult lit section of your local bookstore and pick up an Ellen Hopkins book. You probably wouldn't even have to see her name on the cover to know she wrote it. The first giveaway, of course, is the fact that the book is five hundred million pages long (give or take a few million); the second is that she always writes in verse. As she says in her Amazon.com bio, "writing novels in verse fulfills two needs: writing poetry and writing fiction." Verse it is, then.
Hopkins often experiments with form—for example, in her second novel, Glass, when narrator Kristina talks about her home, the arrangement of the words makes a picture of a house. In Perfect, she doesn't use words to create pictures, but the first page of each chapter forms two poems in two columns. All the words make up a single poem, but the shorter fragments in one column make up a separate one.
For example, on the first page of Cara's first section, the column on the left says, "How/why/where/when/who/what" (1.1-6), and on the first page of Kendra's first section, the right column reads, "Pretty/isn't/good/enough" (2.1-4). Read the whole page, and then read the column with fewer words to find the hidden poem. You'll get double the meaning.
