How’s this for a book tour spin? At many of Harlan Coben‘s appearances, he’s shared the bill with Australian song-writer Missy Higgins; they both speak, she sings and they discuss the creative process of writing books and songs. These events “have been a huge succes,” says Dutton publicity dirctor Christine Ball. Next up: local boy Coben will be honored at an April 16 luncheon by the Friends of the Ridgewood (N.J.) Library, celebrating the library’s 20th anniversary. Long Lost copies in print: 336,000.
