Title: Fifteen (novel)
Content:  Fifteen is a juvenile fiction novel written by Beverly Cleary. It was first published in 1956. It chronicles the perspective of a teenage girl entering her first romantic relationship. The book captures the innocent spirit of life in the 1950s, both through the playfully light storyline and the casual references to convertibles, sweaters, "meeting boys", and soda shops. Regardless, the book remains in print today because its overall theme of difficult adolescent feelings still connects with young readers. In 1958 Fifteen was awarded the Dorothy Canfield Fisher Children's Book Award, after Vermont school children in fourth through eighth grade chose it as their favorite novel.
