In “Dunsmuir,” a newly sober husband buys a hearse to help his wife spread her sister’s ashes, while “The Lesser Horsemen” illustrates what happens when God instructs the Four Horsemen of the Apocalypse to go on a team-building cruise as a way of boosting their frayed morale. In “Brad Benske and the Hand of Light,” an estranged husband seeks his wife’s whereabouts through a fortuneteller after she absconds with a cult, and the returning soldier in “Homecoming” navigates the strange and ghostly confines of his hometown, as well as the boundaries of his own grief. With grace, imagination, and a brazen gallows humor, Folk Songs for Trauma Surgeons merges the fantastic and the everyday, and includes new work as well as award-winning favorites.
