According to Chuck Palahniuk's website this book is about the following:

"*Originally released in paperback in 1999, the first hardcover edition of Invisible Monsters was published on June 11, 2012. This edition is a restructured version of the novel, entitled Invisible Monsters Remix. It contains a new author's introduction, explaining that the linear structure of the first edition was not the novel's original intent. Instead, this new edition of the novel presents the chapters in mixed order with instructions on which chapter to read next, similar to Choose Your Own Adventure books, and new chapters have also been added. (Wikipedia.org)
"Injected with new material and special design elements, the Invisible Monsters Remix fulfills Chuck Palahniuk's original vision for his 1999 novel, turning a daring satire on beauty and the fashion industry into an even more wildly unique reading experience. Laced in are new chapters of memoir and further scenes with the book's characters. Readers will jump between chapters, reread the book to understand the dissolve between fiction and fact, and decipher the playful book design.*" Source: http://chuckpalahniuk.net/books/invisible-monsters-remix

Better put it is a book like "Naked Lunch", but with remix its choose your own adventure, super graphic but a damn good read.

Plotish? (original term by yours truly for a pseudo-plot):
Its a coming of age tale.... no wait.....hhhhmmmmm, GOT IT! Its Thelma & Louise, if one was a man and the other missing most of the bottom of their face and they were related but didn't know it, aaannnnnddd no Brad Pitt..... so yeah. That's why I still read Chuck, none of this books are surface value.... hell try to explain "Fight Club"????
