Growing Up in the Gutter offers new understandings of contemporary graphic coming-of-age narratives by looking at the genre's growth in stories by and for young BIPOC, LGBTQ+, and diasporic readers. Through a careful examination of the genre, Ricardo Quintana-Vallejo analyzes the complex identity formation of first- and subsequent-generation migrant protagonists in globalized rural and urban environments and dissects the implications that these diasporic formative processes have for a growing and popular genre.

While the most traditional iteration of the bildungsroman—the coming-of-age story—follows middle-class male heroes who forge their identities in a process of complex introspection, contemporary graphic coming-of-age narratives represent formative processes that fit into, resist, or even disregard narratives of socialization under capitalism, of citizenship, and of nationhood.

Quintana-Vallejo delves into several important themes: how the coming-of-age genre can be used to study adulthood, how displacement and international or global heritage are fundamental experiences, how multidiasporic approaches foreground lived experiences, and how queerness opens narratives of development to the study of adulthood as fundamentally diverse and nonconforming to social norms. Quintana-Vallejo shows how openness enables belonging among chosen families and, perhaps most importantly, freedom to disidentify. And, finally, how contemporary authors writing for the instruction of BIPOC children (and children otherwise affected by diaspora and displacement) use the didactic power of the coming-of-age genre, combined with the hybrid language of graphic narratives, to teach difficult topics in accessible ways.
