Thanks so much!
Looks like there's a later volume of stories free, too:
Stories from the Flannery O'Connor Award: A 30th Anniversary Anthology: The Recent Years (Flannery O'Connor Award for Short Fiction), ed. Nancy Zafris
Stories selected from winning volumes published in the series' past fifteen years, from Frank Soos's Unified Field Theory (1998) to Hugh Sheehy's The Invisibles (2012).
