The poems in Katherine Soniat's new collection, The Swing Girl, weave emotion's 'spray going farther than thought' with the 'bedrock things' of the trod-upon world. These poems eddy and pool in unpredictable and often surprising ways, much as the mind moves in its twilight state between waking and sleep. The fluidity of their cadence and the luminosity of their imagery carry the reader to the wellspring of poetry itself, that deep delight of which Robert Penn Warren spoke, whose source is, in Soniat's words, 'beauty on its way to being mystery.'
