Sorry, sister. There’s a new girl in town. Amy Tan, best-selling author of The Joy Luck Club, wasted no time dethroning Terry McMillan from her No. 2 berth. Sales for Tan’s latest, The Bonesetter’s Daughter (575,850 copies out of the gate), benefited from an author appearance on PrimeTime Thursday and a glowing review on National Public Radio’s All Things Considered. The energetic author, who plans to blanket the country with a 32-city tour over the next two months, may kick John Grisham out of his house on the top of fiction’s hill.
