Also in 1993, O'Nan was able to find a publisher for his second book, and first novel, "Snow Angels"—based on the story "Finding Amy" from "In the Walled City"—when the manuscript earned him the first Pirate's Alley Faulkner Prize for the Novel, awarded by the Pirate's Alley Faulkner Society of New Orleans. In 2007 "Snow Angels" was adapted for a film of the same title, directed by David Gordon Green, who also wrote the screenplay, and which starred Sam Rockwell and Kate Beckinsale.
