A New York Times bestselling novel of desire, secrecy, and sexual identity, In One Person 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 of In One Person, 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 of "terminal cases," The World According to Garp.

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