“The Only Woman in the Room’ by Marie Benedict novelizes of the life of Hedy Lamar, who, before Hollywood fame, was a spy. It may be this year’s first breakout hit. “The Lake on Fire” a story by Rosellen Brown about Jewish immigrants, is also getting attention. “Harry’s Trees” by Jon Cohen, a tale of twisted friendship and “Where the Crawdads Sing”, a slice of southern Gothic by Delia Owens, are two other unknowns that have found a wider readership.
