Coyote offers intimate shadings on a story that will be familiar to fans of literary biography or anyone who has ever attended a 12-step recovery program ... The author...puts his subject’s journal entries and family correspondences to good use ... Mr. Dowling is a discerning and sympathetic, if occasionally starchy, guide through Shepard’s oeuvre. The connections to O’Neill and Samuel Beckett, in particular, ring true ... While this volume digs deeper still into the mind and adventures of the playwright, eight years gone, you get the sense that there’s more to come.
