Zombie stories usually begin with the dead rising. Dave Bonta's "Undead" starts earlier, with an accusation aimed at the reader: "If the dead can't rest, / it's because we won't let them." The whole argument is packed into those two lines, and the remaining eleven spend their time proving it.
The proof begins with a short catalogue of how the living behave. "We storm, / we harry, / we decry, / we implore." Each verb gets its own line, so they land like repeated knocks on a door. The tone also slides. To storm and to harry are military, even predatory words, since harrying suggests hounding something down. To decry is to condemn, and to implore is to beg. The list moves from attack to plea, and the poem seems to suggest that begging belongs to the same family as attacking. Even sincere grief, the wish to call someone back or demand answers, may be a form of disturbance. The poem never says this outright. It leaves it in the order of the verbs, and no "and" joins them, so they pile up without a pause.
Then the poem changes gear. "We make them star / in our horror shows" is where the dead become the objects of a deliberate act, and "star" is a sharp choice. It is a word from film credits, and it makes the dead sound like unwilling actors cast in roles they never auditioned for. The sentence also sprawls. Where the earlier lines were clipped, this one stretches across six lines and runs on, much like the thrill it describes: "for that surge of adrenalin / that lets us know / we're alive." "Adrenalin" is a clinical word dropped among plain ones, and it exposes the motive. We are not really afraid of the dead. We want the sensation of being afraid, because it proves we are living. The dash after "alive" works like a held breath before the sting.
The sting comes in the last two lines: "as if they our dear departed / were the ones out for blood." The syntax is slightly off. "They our dear departed" has no commas, so the phrase drops in like a muttered aside, reminding us who these supposed monsters used to be. "Dear" is the poem's only tender word, and it arrives just after we have been shown how little tenderness we offer. "Out for blood" is a worn-out idiom that the poem brings back to life. Blood is what movie zombies hunt, but it is also what races through us when adrenalin hits. The phrase accuses the living of the appetite we pin on the dead.
Formally, the poem is free verse: one stanza, thirteen lines, no regular meter and no end rhyme. Its rhythm comes from line length, with blunt, short lines in the middle and longer, looser ones where the thrill-seeking is described. Sound does some of the work rhyme might have done. The vowels in "storm," "implore," "horror" and "for" echo one another with a low, growling r, and "harry" and "decry" share a closing -ry. The language is plain and conversational throughout, which makes the accusation harder to dodge.
The poem matters because it turns a familiar genre into a mirror. Horror fiction usually puts the threat outside us, in the grave or the dark. Here the threat is our habit of refusing to let go, and of turning loss into entertainment. The title gives one more twist. If we need a jolt to feel alive, then "undead" might describe the living as well as the dead. That is my reading rather than something the poem states, but its final image invites it. In under a hundred words, the poem flips the monster story so that the haunting is something the living do to the dead.
