Two books that had already received high honors were honored again today when the winners of the Dayton Literary Peace Prize were announced. "Far From the Tree," Andrew Solomon's book about children who are vastly different from their parents, and how that affects their upbringing, won the nonfiction award. And Adam Johnson's fascinating peek inside North Korea, "The Orphan Master's Son," won the prize for fiction. Solomon had already won the National Book Critics Circle Award, and Johnson's book had won the Pulitzer Prize.

The Dayton Literary Peace Prize carries an award of $10,000 and will be presented Nov. 3 in Dayton, Ohio.

This year's runners-up were "Billy Lynn's Long Halftime Walk," by Ben Fountain (also winner of a National Book Critics Circle Award) and "Devil in the Grove," by Gilbert King.

The list of nominees had included Louise Erdrich's novel, "The Round House," winner of a National Book Award and a Minnesota Book Award, and a memoir of Romania, "Burying the Typewriter," published by Graywolf Press.

The peace prize is awarded annually to books that use the power of literature to foster peace and understanding.
