Ron Koertge eagerly tries his talented hand at Flash Fiction. In “BFF,” a teenage girl from the near-future orders friends from Amazon. A few pages later, a robot who travels what is left of the world and observes through “well-engineered eyes” claims that the sound of turbines is his lullaby. A fed-up daughter finds a foolproof way to do away with her awful mother, while in “Jesus Dog” a mysterious animal helps a broken man recover. A page from Lois Lane’s diary reveals a shocking secret. Many mothers and daughters will see themselves in Ron’s version of the Persephone & Demeter story. Readers are ushered aboard a mysterious train and later invited to listen in as a teacher chats with a peculiar student named Oliver Oliver. A distant relative of Leda takes her boyfriend to the arboretum with grisly results, and Mr. Weenie tells his daughter how he and her mother met. “Sex World,” the title story, turns out to not be about sex at all, but heartbreak. In these and dozens more, Ron lives up to his reputation as someone who is funny the way the truly serious often are.
