There is a paperback on my bookshelf that doesn’t exist, but it managed to change my life anyway. I found this book among other homely paperbacks on the ninety-nine cent cart at the Montague Book Mill, a used bookstore in Massachusetts’ Pioneer Valley. True to its slogan -- “Books you don’t need in a place you can’t find” -- nothing stocked is guaranteed to be there again, making this book a quintessential one-of-a-kind find. What arrested me first was its size: a little smaller than one of the classic mid-forties Penguin editions, narrow and flexible, ideal for slipping into a purse or pocket. What caught me next was its barefaced plainness. The jacket was entirely white, the cover crinkled from its stint as a coaster. Its title was an italicized Times New Roman second-cousin. It appeared to be a self-published book; inside, the author had written a note in an unassuming small-caps scrawl, wishing a friend the best of luck with his own career. Although I have searched the title and the author more than once, the novel remains nonexistent. Unlike I’d first imagined, this author had no website or author’s platform. Search engines brought up many potential origins of the title (it has a fantasy flair) but an exact match remained elusive. All signs point to the author not having “made it” as we expect authors to ascend in this century’s frenetic flux of multimedia attention. In effect, here lies the only copy; rest in peace. This novel has been on my bookshelf ever since, surrounded by the greats: Dante Alighieri and Leo Tolstoy, Emily Dickinson, William Faulkner. But this book has a special status compared to its neighbors, albeit an infamous one. It is my bad-mood effigy; I turn to this book for an adrenaline shot of self-indulgence whenever I’m in the throes of apathy, bad writing, and rejections. Simply put, the writing of this book is bad. In fact, it’s often laughably bad, an unremarkable and derivative species of the speculative genre. In my more magnanimous moments (or so I delude myself), I think self-righteously, This author -- the nerve! The self-published pretension! As my literary voodoo doll, I believed I could turn to this novel as a concrete specimen of the written word that was -- undeniably -- inferior to my own work. But books do not defer meekly to the morals we have assigned them. A bad book, so-called, has just as much to teach us as a good book. It is often a far better teacher than any work that is uniformly artful, where excellence disguises the nuts and bolts of craft. A bad book also teaches us something a better book cannot: humility. Not the humility of resignation -- that of admitting that we will never be very good at what we do, no matter how earnestly we try. Such humility can easily morph into the indulgent self-flagellation that either demands the commiseration of friends or brings our vocation to a standstill, where thereafter we are those people who petulantly claim we “could have been somebody.” Rather, it’s the humility of acknowledging that time and effort lead to changes in our abilities as writers. Instead of ascribing a moralistic verdict of good or bad, less or more, we humbly acknowledge that nothing more could be asked of us than what our creations can attest to at the time. The great works of literature are all relatively alike in their excellence. Their perfection is consummate, constantly out of reach. We become comfortable saying, amused and defeated, “I’m no Shakespeare,” as if that is that. But every bad specimen of writing is lit up by the harsh fluorescent lighting of reality. Each pockmark, scar, and slip-up is visible; we have our favorites to trot out in conversation like ghouls in chains. Moreover, what makes for a bad book is a constantly shifting parameter. Is a book bad if it is merely written poorly? Is a book bad if it’s successful with the masses? (Fifty Shades of Grey, for instance, being one of those “bad” novels that is known -- if not read -- by everyone.) But my own unique bad book quickly transformed from a voodoo doll to a mirror. This person’s writing is cheap and unmarketable, I start to think -- and before I finish the thought: So was your writing a year ago. A week ago. Yesterday. Bad books remind us of our failings and that such failings are always closer to us than we imagine. As writers, we have to be our own best advocate; we have to invest in the underdog. And by the same token, we must be our first critic, our arch nemesis. Anne Lamott posits in Bird by Bird that radio station KFKD ("K-Fucked") is playing in our heads each time we write, with “the endless stream of self-aggrandizement” blasting in the speaker of our right ear, while “out of the left speaker will be the rap songs of self-loathing.” We can tune these out but not turn them off. Similarly, Orson Scott Card contends in How to Write Science Fiction & Fantasy, “Writers have to simultaneously believe the following two things: 1. The story I am now working on is the greatest work of genius ever written in English. 2. The story I am now working on is worthless drivel.” The bad book on my shelf reminds me that I will contend with both ideologies at any given moment, and at any given moment they are true. We are destined to be continuously judged and ranked on a scale of lesser to better in our work. In reality, art is a highly competitive realm with no real rules. By turns, we will be winning in the arena, and we will be losing. And KFKD is always playing in the background, whichever speaker is blaring louder at this moment. And thus the most marvelous lesson of the nonexistent book on my shelf: that of artlessness. We do not write good books or bad books. We are all teachers, capable of leaving a lesson behind.
