Last Thursday I went to the launch party for Katie Green’s Lighter Than My Shadow (just published by Jonathan Cape) a graphic memoir in which she tells the story of her descent into and recovery from anorexia (and quite a bit besides). It is a big book, 524 pages in all, which somewhat belies its title, yet I read the whole thing in one sitting. I know I’m not alone in having done this: once you start, it is very hard to stop. It is compelling but a hard book to read: I felt the tears welling up several times. It is also a great book. The graphic format works perfectly for the story and Katie – a terrific illustrator – has managed to convey very vividly some little part of what it felt like from the inside. The black cloud of despair, the screaming monsters in the head, the desperate urge to control, control, control and the sense of alienation from those closest to her, the pain she knows she’s inflicting on them but can’t help doing so.

When she spoke at the book launch Katie said that she hadn’t written the book to help anyone. Nevertheless, I’m sure it will help one very large group of people, the people who can’t imagine what it is like for someone in her position, who can’t understand the sense of compulsion, and why the sick person can’t just “pull themselves together”. In giving voice to this inside, Katie has pulled off something comparable to what William Styron did for depression in Darkness Visible. That’s a pretty high standard of comparison, I know, and I’m feeling swayed by the immediate experience of just having read Lighter Than My Shadow, but I don’t think it an unfitting one.

I should disclose a slight interest. I know Katie slightly (she’s a friend of one of my children) and a photo I took is on the cover flap. So I’m not entirely impartial. Still, I think this is, objectively, a very great achievement. And I don’t mean to relativise in a way that suggests that it is great for someone who has gone through her experience to have produced something this good. I mean that it would be great for anyone to have created this, even though her experience is a condition of having done so. Anyway, people out there, this is a book that most of you ought to read. You can get it at Amazon of course, but better to buy from somewhere else. (The Guardian had a feature on the book last week.)
