Wally Lamb's HEFTY new book--I KNOW THIS MUCH IS TRUE--centers on a pair of identical twin brothers--Dominick and Thomas Birdsey. Born in the closing moments of 1949 and the opening minutes of 1950--the boys mirror each other physically. But mentally they're quite different. Thomas slips into paranoid schizophrenia while Dominick struggles with depression. Lamb's 900 page book explores life's big issues such as: child abuse, mental illness, AIDS, racism and making peace with the past. His previous book--SHE'S COME UNDONE--shot to number one on the NY TIMES BESTSELLER LIST after Oprah Winfrey selected it for her book group. Wally Lamb told Minnesota Public Radio's Greta Cunningham he used Hindu myths, Italian history, modern-day psychology and volumes of other books to research I KNOW THIS MUCH IS TRUE.
