Invisible Monsters is a novel by American writer Chuck Palahniuk, published in 1999. It is his third novel to be published, though it was his second written novel. The novel was originally supposed to be Palahniuk's first novel to be published, but it was rejected by the publisher for being too disturbing. After the success of his novel Fight Club, Invisible Monsters was given a second chance, and a revised version of it was published. The first edition was released in paperback in 1999, and on June 11, 2012, it was published in hardcover, in a revised edition titled Invisible Monsters Remix (ISBN 978-0393083521).
