New author Ruvanee Pietersz Vilhauer won the 2018 Iowa Short Fiction Award by hewing close to the theme of the culture shock experienced by immigrants to the United States from Sri Lanka. In “The Water Diviner and Other Stories,” these uprooted people react and adjust - or fail to adjust - in a wide variety of ways to the strange American customs and culture. Their stories are told in effective and unadorned language; the emotions and tensions are plainly depicted, sometimes lurking below the surface, sometimes erupting strongly into the open.

There are the childhood friends visiting in young adulthood, in which old grievances prove surprisingly durable (“The Beauty Queen”); in “The Water Diviner” a woman emerges from the thrall of a televangelist to turn once again to her “real” life when a prophecy turns false. In “Sunny’s Last Game” immigrant parents find reason to back off their tendency to over-protect their junior-high student son. The urge arose from perceived slights inflicted by classmates.

In one of the more interesting pieces - among 15 absorbing stories collected here - “The Lepidopterist” portrays the struggles of a girl who treats everything she reads and everything everyone says as strictly - abnormally - literal. However she grows to become a scientist spurred by her childhood fascination with butterflies. She triumphs over the prejudices she faced as a young girl, and this is often the case with other characters whose talents and attitudes serve them well and provide the basis for success in life, in the U.S. or Sri Lanka.

It is plainly the skill in executing these stories that won Ms. Vilhauer the award. Pacing and structure, characterization and treatment of theme, all bear the stamp of an accomplished fiction artist. These stories feature both variety and clarity: characters are found and portrayed in very different circumstances and stages of the assimilation process - often within a single story. It’s a pleasing, impressive display taken together. Congratulations once again to the jury giving the Iowa short fiction awards. This is another deserving winner. ( )
