Often compared to such classic novels as Lolita, The Story of O, and Tropic of Cancer, and first published by the legendary Barney Rosset, Butterflyby Paul Loewen is a "brilliant meditation on obsession and desire, a tour de force of erotic storytelling and literary invention" drawn from the life of Pinkerton in the renowned Puccini opera of the same name.

Paul Loewen lives with his wife in Paris. Butterfly is his first novel.
