The book is, primarily, a linguistic investigation into the possibility that the Johannine farewell discourse is the product of multiple hands. L. Scott Kellum uses the latest linguistic tools and applies them to the very old question of unity. In doing so, he accesses a large portion of Continental scholarship that is currently unavailable to English speakers. He concludes, on linguistic and literary grounds, that John 13:31-16:33 (the so-called farewell discourse) was written by one man at, essentially, one time.
