Eight words, three lines, and a gentle tease at the reader's expense. Dave Bonta's "Bookworm" gives us a title that names someone lost in print, then spends its whole length trying to pull that someone out of the book. The poem turns on a single metaphor, "the brown book / of a wing," and then an order: "look up."
Start with the title. A bookworm is both a person who can't stop reading and, in the older sense, a creature that gnaws its way through paper. The poem never says which it means, and both are in play. If we are the bookworm, we are the one hunched over the page when the poem interrupts us. The brown, papery wing also seems to belong to that dusty, bookish world. Judging by the colour and the word "wing," the image may be a moth, though the poem leaves the creature unnamed. A closed wing, folded flat and brown, does look like the cover of an old volume, and a wing opening and closing has the rhythm of a book being read.
The metaphor is neatly reversed. We usually compare nature to writing only when we're being poetic, but here the comparison comes from the ordinary object in our hands. The wing is a book, with its own cover, its own pattern like faint print, and its own pages for anyone who cares to read them. There is a quiet pun in the language we already use for books, since a page is also called a leaf, a word borrowed from trees. By calling the wing a book, the poem hands that borrowed vocabulary back to the natural world.
The construction is tiny but deliberate. The lines run three syllables, three syllables, then two, so the poem seems to shrink as it goes, like a breath let out. There is no capital letter and no full stop, which keeps the poem open-ended. The first line stacks two heavy stresses, "brown book," so the image lands with a thud, like a book set down on a table. The second line begins lightly with "of a" and rises to "wing," which makes the word feel like it has just taken off. Line breaks do much of the work. "Book" ends the first line, so for a moment we think we're simply reading about a book. Only when the next line arrives do we learn it's a wing.
Then comes the dash, the poem's hinge. It is a small pause where the description stops and the command begins. The sound pattern is quietly clever too: "book" and "look" make a true rhyme, even though they sit at opposite ends of the poem. The rhyme links the two ideas. The thing we are reading and the thing we are told to do are bound together, and one word has to give way to the other. "Brown" and "book" share their opening consonant, so the first line has a tight, almost bound sound, while "look up" ends on an open vowel and a lifted lip, as if the mouth itself were raising the eyes.
"Look up" is the most interesting phrase because it can be read several ways. It is a plain instruction to raise your eyes from the page. It is also what we say when we consult a reference, as in "look it up," which lets the wing become something to be checked and studied. And it carries a faint note of hope, as in "things are looking up." Each reading is a little different, but they all point the same way, away from the page and toward the world.
That is what makes the poem worth reading. It is a piece of writing that tells you to stop reading. The poem knows it is made of words on a page, and it uses those words to send us toward something that no page can hold: a real wing, present in real light, which is not lying in front of us at all but somewhere above. The white space after "up" serves as the last line, the moment when the reader's eyes lift and the poem finishes in the world rather than on paper. In the manner of haiku, it trusts a small image and a sudden turn to do what a longer poem might need pages for.
