1On a collective level, the human diaspora is incalculable. Our leaving and resettling are as ancient as we are, whether immigrant, refugee, exile, or pioneer. In Splinter, Susan O'Dell Underwood's poems trace the unique experiences of the Appalachian diaspora. Splinter suggests the deep ambivalence in the breaking away, a sundering which can never be mended. These poems test the emotional spectrum, weighing the joyful possibilities and sorrows of leaving against the obligation of those who stay "home," grateful yet bereft in an altered place.
