Critic Sam Anderson describes the book as follows:[1]
The book is subtitled "A Novel in Verse," but—as usual with Carson—neither "novel" nor "verse" quite seems to apply. It begins as if it were a critical study of the ancient Greek poet Stesichoros, with special emphasis on a few surviving fragments he wrote about a minor character from Greek mythology, Geryon, a winged red monster who lives on a red island herding red cattle. Geryon is most famous as a footnote in the life of Herakles, whose 10th labor was to sail to that island and steal those cattle—in the process of which, almost as an afterthought, he killed Geryon by shooting him in the head with an arrow.
Autobiography of Red purports to be Geryon's autobiography. Carson transposes Geryon's story, however, into the modern world, so that he is suddenly not just a monster but a moody, artsy, gay teenage boy navigating the difficulties of sex and love and identity. His chief tormentor is Herakles, a charismatic ne'er-do-well who ends up breaking Geryon's heart. The book is strange and sweet and funny, and the remoteness of the ancient myth crossed with the familiarity of the modern setting (hockey practice, buses, baby sitters) creates a particularly Carsonian effect: the paradox of distant closeness.
