In One Person is a 2012 novel by American author John Irving, his 13th since 1968. The book was published on May 8, 2012 by Simon & Schuster, and deals with the coming of age of a bisexual man and his coming to grips with his sexual identity.
In One Person is narrated by central character Billy, a bisexual novelist. Billy’s story is told through multiple time periods and shows him initially as a teenager with crushes on the “wrong people,” but also showing his coming of age.
Irving came up with the idea of writing a book about a bisexual character while thinking “what if,” also commenting that the subject matter of bisexuality was familiar to him, having had fleeting crushes on boys while growing up. He also remarked on the subject of the AIDS epidemic of the 1980s when he wrote that he and several family members of homosexual men had only discovered the sexual orientation of these men due to their being diagnosed as having the disease and dying of it. Irving has stated that while it had taken him seven to eight years to conceptualize the book, he felt that the novel’s actual writing process was relatively fast and that due to his experiences in New York, did not have to do as much research.
