Porter's work has had a great impact on juvenile audiences. Young readers voted The Crazy Man across Canada as their favourite book of the year. Her books are distinguishable from other children books as their themes deal with real-life issues and are often based on serious subjects, and are written in verse rather than conventional prose. They involve difficult and challenging experiences that children have encountered or will encounter in their lives, and are stories that many children can relate to. A prime example is The Crazy Man, which deals with the abandonment of one parent or sometimes both, thus telling the story of how people heal from tragedy and what they do to arrive at the point of healing, and even of gratitude.
