Query: you'll find it used soon enough...

Despite the hip, appealing jacket and auspicious credentials of the author, this book disappoints. It feels like an academic toss-off, designed for the layperson with a fleeting interest, who will leaf through it like a magazine. To swim through the author's disjointed and often autobiographical slough to arrive at the occasional chunks of interesting stuff is simply not worthwhile. On page 9, the author describes his attitude toward his doctoral thesis (...I stayed up, slept late, frequented cafes in the long afternoons, wrote and unpublished novel and an unperformable play, watched far too many old movies, and diligently avoided my supervisor...) Replace 'supervisor' with 'lit agent', and we may have discovered Newton's approach to book writing as well.It's a wonder that a writer could take such a fascinating subject matter and make it so annoying.
