Example Input: SWEET DREAM BABY isn't grand fiction, but it's an engrossing story with a vivid sense of time and place. The author has pulled off the difficult trick of showing the world through a child's eyes and yet supplying the reader with adult perceptions. Parts of the plot are predictable, but at the conclusion predictibility flies out the window. The novel may be set in the '50s, but this is not a Leave-it-to-Beaver ending.Anyone with firsthand experience of the fifties may have to stretch their suspension of disbelief regarding certain sexual behaviors by the protagonist's aunt in relation to her nephew, but the author has traded a bit of unlikeliness for a gimmick that elevates this novel from the usual coming of age story.
Example Output:
Positive
