GUESS WHO'S COMING TO DINNER?, by Brenda Lane Richardson. Wildcat Canyon Press/Circulus Publishing Group, Inc., 2000, Berkeley, Calif., $14.95.

Brenda Richardson is an award-winning African-American writer and partner in a 16-year marriage to a Swedish-American Episcopalian priest. She set out nearly a decade ago to interview couples like herself, and document the worldwide shift toward mixed marriages.

The result is "Guess Who's Coming to Dinner?" a book with simple messages and timeless wisdom about mixed marriages based in, but not limited to, the United States. Fifty-five people were interviewed here to cover every conceivable combination of inter ethnic, interfaith and interracial relationships, from Scottish and Native-American, African-American and Japanese, to Mexican and white Anglo-Saxon.

"The good news," Richardson says, " is that when people bring cultural differences to a relationship, it's a bit like each individual bearing a dowry -- trunks laden with gifts."
