Rain in a desert is usually good news, but Dave Bonta's six-line poem treats it as an upheaval. The speaker says "my body is like a desert / in the rain," and what follows is less a description of a feeling than a small story. A river that had been dead gets up, leaves the bed it was lying in, and goes off in search of somewhere better to sleep. The central idea is that renewal and abandonment can be the same event: what wakes the body up also makes something leave it.
The title does a lot of the work. "Desertion" contains "desert," and the poem plays on both meanings, a dry place and an act of leaving. The opening simile gives us the first, and the second and third stanzas give us the second. The river deserts its bed, and the speaker's body is, in some sense, the place that has been deserted. The poem never says what is being left, whether a lover, a way of life, or an old self gone numb, so the reader has to decide. The imagery nudges us, though. A "bed" is both a riverbed and the place where people sleep, and "a full bed" suggests somewhere crowded, with no room left. Judging by these words, something has become too fixed or too full to hold what is rising.
The first image is more unsettling than it looks. Parched ground is hard, and when rain finally arrives it often cannot soak in; it races off and gathers in dry channels. The simile suggests a body that cannot quietly absorb what arrives, whether desire, grief or relief, and so it floods. The "dead river" is probably one of those empty channels, and the phrase is a small paradox, since a river is by nature something that moves. "Raised up" carries a hint of resurrection, a body climbing out of its grave. Bonta follows it at once with a harder verb, "broke out," which sounds more like a prison escape than a revival. The river is reborn and on the run in the same breath.
The form behaves in a revealing way. There is no punctuation and no capital letter anywhere, and the poem is built from three couplets. That sounds tidy, but the grammar will not stay inside the stanzas. The first couplet is a complete statement that comes to rest, as if the speaker were laying down a fact. The second and third form a single sentence, carried along by "and broke out… to run… and find." That sentence spills across the gap between stanzas the way the river spills over its banks. Even the line break in the opening couplet is a small surprise: "in the rain" waits alone on its line, so the weather arrives as a delayed, almost deadpan correction to the desert.
There is no rhyme, but sound still binds the poem together. "Bed" ends two lines and changes character the second time, from "full bed" to "better bed," where the f and b sounds of "full" and "better" lean on one another. The repetition turns the escape into a comparison: the river leaves one bed because it hopes for another. The hard b of "broke" and "bed" gives the middle stanza its force, while the last line ends on a soft, unstressed "in." The poem finishes not with a crash but with the sound of someone settling. The energy of "run" and "horses," which suggest speed and wildness, drains into sleep. It is an odd ending, because the escape is not for adventure but for a better place to lie down.
That ending is what makes the poem worth remembering. A less careful poem would celebrate the flood or mourn the emptiness. Bonta does neither. He lets the river be restless and practical at once, wild enough to run with horses yet driven by an ordinary wish for comfort. The speaker never says whether they feel abandoned, freed, or both. In six short lines the poem holds a desert, a flood, a resurrection and perhaps a breakup, names none of the last three outright, and trusts the single word of its title to tie them together.
