Cosmo: The Brief, Wondrous Life of Oscar Wao is a prose novel by Junot Diaz. The book, published in 2007, examines the tribulations of a family over he course of three generations and two countries (the Dominican Republic and the United States). It is an exceptionally well-written book, full of both compelling characters and cultural history. One element which runs through the book is the title character’s love for genre. From comic books to Lord of the Rings to role-playing to anime and more, Diaz seamlessly weaves this motif into the essence of the narrative. Geek culture becomes as much a part of the novel’s language as the phrases of Spanish scattered throughout.
