Storm and household blur into one in "Soundless Thunder," until the boy at its centre can no longer tell which is which. He watches grey clouds gather over a valley while his father rages in the hallway, and the poem keeps asking whether a given noise comes from the sky or from the house. "Was that the shout of thunder, or the clattering of his bones?" he wonders. A few lines later, a rolling wave of thunder might be "a bottle rolling across the wooden floor." His closing admission, "He couldn't tell anymore," is the emotional core of the piece. Living with fear has worn away his ability to separate outside danger from the danger indoors.
The poem makes this confusion physical through its central metaphor. The storm clouds are "grey wolves" that pace, patrol, growl and crash into one another, and the lightning is the white "tendrils" that spring from their "broken façades." The word "façade" is worth lingering on, because a façade is something put up to hide what lies behind it. The same cracking happens at home, where vases break and the father's voice turns familiar and threatening. The wolves are never explained, but they fit a household in which something predatory has taken over. The boy, meanwhile, is not a wolf but prey, curled up "like a snake afraid of humans coming to kill him." That simile is a clumsy, overlong line, and the length helps. It sprawls across the page the way his fear does.
There is no rhyme and no steady metre. The poem is free verse, and its rhythm comes from contrast between long, breathless lines and abrupt short ones. The snake sentence and the description of the mother's story run on and on, while "Crash!" and "He couldn't tell anymore" land like slammed doors. The shift to past tense after the opening also matters. The poem begins in the present of the storm, then slides into memory, as if the boy escapes into the story his mother once told him.
That story is the poem's most important device. Mother's fable of the thunder who "couldn't sing" gives the boy a way to read his own situation, and he takes it literally: "He was thunder, voiceless until everything was bleak." Here the title begins to make sense. Thunder is the loudest thing in the sky, yet in the fable it has been robbed of its voice, so "soundless" describes a pain that cannot be spoken. The poem also leaves a gap about the mother. We hear only her voice "maneuvering the ups and downs" of the tale, remembered rather than present, and the poem never says where she is now.
Colour carries much of the meaning. Grey belongs to the wolves, the sky and, strikingly, the father, who drowns in "the shimmering grey mirage that wrapped around him like a shroud, reflecting the grey sky overhead." This is a moment of unexpected sympathy. The father is not only a source of noise but a man lost in his own misery, and the boy sees him as trapped rather than simply cruel. White, by contrast, is the colour of lightning and of pain, since the flash on the window is "as intense as the white hot pain" in the boy's wrist. The poem mentions this wound only once and moves on without comment, which makes it more unsettling. Light and hurt are placed side by side, and the reader is left to draw the connection.
The ending is deliberately open. In the fable, the lightning "hurled itself like a javelin" and called the thunder to follow, and the poem repeats that sentence before concluding: "And it did. / And he did." What does the boy follow? The poem does not say. It could be an escape from the house, the finding of a voice, or something darker. The repeated phrase and the narrowing vision ("slivers of his dull window") leave room for all of these readings, and the lines have a quiet finality that is hard to settle. The ambiguity seems less like evasion than honesty about how hard it is to know where such a moment leads.
What makes the poem significant is its refusal to explain. It never uses the words for what is happening to this boy. It lets a children's story, a storm and a handful of broken objects carry the weight, and it shows how a fable can become a way of understanding, and perhaps surviving, a frightening home.
