"Object permanence" refers to the early developmental stage in which the child learns that the world exists independently of one's own ability to perceive it. In this, her first full-length collection of poems, Michelle Gil-Montero unveils the elusive debris of daily life in order to invoke, paradoxically, its impermanence. These poems summon the liminal world of early motherhood, of early morning, of seasons in transition. Inhabiting a terrain of post-industrial landscapes at once familiar and not--a space where what isn't encroaches on what is--Gil-Montero's pitch-perfect, emotionally resonant lyric lines pressure the expressive possibilities of language. Sound hovers on the verge of becoming object. Object threatens to evaporate into sound.
