David Hernandez's Suckerpunch is considered a "coming of age" novel which depicts events which could realistically happen (Realistic Fiction). Technically called a Bildungsroman, referring to a novel which details the moral and psychological growth of the main character, Suckerpunch follows Marcus (the protagonist and narrator) through the summer before his senior year in high school. He is struggling with his feelings regarding his father (he wants him dead). Given that some parents have abused their own children, the novel illustrates the reality of abuse for some children.
The novel's title illustrates the blows (strikes/hits which seem to come from nowhere) which face adolescents as they move from teenagers to adults. Paralleling the idea of the unknown, the abuse the characters in the novel face also illustrate the importance of the title.
Sucker Punch by David Hernandez is realistic fiction.
