IN PRAISE OF FORGETTING: Historical Memory and Its Ironies, by David Rieff. (Yale University, $16.) Rieff, who as a journalist witnessed firsthand the atrocities of the Bosnian war, outlines a humane case against memorializing tragedies.

RAZOR GIRL, by Carl Hiaasen. (Vintage Crime/ Black Lizard, $15.95.) A cast of comic, only-in-Florida characters carry out this novel's elaborate farce: Lane, a Hollywood agent kidnapped in error after a fender-bender; his client, the star of a lowbrow reality show; and the woman of the title, who takes Lane hostage. Hiaasen's prose helps to keep "everything at the right temperature," our reviewer, Terrence Rafferty, wrote. "In Florida, you have to know how to stay cool." DIMESTORE: A Writer's Life, by Lee Smith. (Algonquin, $15.95.)

One thing about the South that will never change? "We Southerners love a story," Smith writes, "and we will tell you anything." HOMEGOING, by Yaa Gyasi. (Vintage, $16.) Starting in 18th-century Ghana, the lineages of two half sisters - one married to a white man and living in comfort, the other sold into slavery - unfold in Africa and the United States.
