In One Person is a New York Times bestselling novel of desire, secrecy, and sexual identity. It is a story of unfulfilled love—tormented, funny, and affecting—and an impassioned embrace of our sexual differences.

Billy, the bisexual narrator and main character, tells the tragicomic story (lasting more than half a century) of his life as a "sexual suspect," a phrase first used by John Irving in 1978 in his landmark novel The World According to Garp.

This novel is a poignant tribute to Billy’s friends and lovers—a theatrical cast of characters who defy category and convention. Not least, it is an intimate and unforgettable portrait of the solitariness of a bisexual man who is dedicated to making himself "worthwhile."
