What is the alliteration and effect of this poem.? "uncoiling" by pat mora with thorns, she scratches on my window, tosses her hair dark with rain, snares lightning, cholla, hawks, butterfly swarms in the tangles. she sighs clouds, head thrown back, eyes closed, roars and rivers leap, boulders retreat like crabs into themselves. she spews gusts and thunder, spooks pale women who scurry to lock doors, windows when her tumbleweed skirt starts its spin. they sing lace lullabies so their children won’t hear her uncoiling through her lips, howling leaves off trees, flesh off bones, until she becomes sound, spins herself to sleep, sand stinging her ankles, whirring into her raw skin like stars.
