Three's a charm—the national hardcover list rarely has so many first-time novelists at once. Allison Pearson's I Don't Know How She Does It is the third debut novel on the current PW fiction hardcover list; Knopf and author are surely hoping for as good a run as the other two (The Lovely Bones and The Nanny Diaries). The book has benefited from stellar reviews (a starred one in PW among them) and lots of attention in national magazines with specific appeal to women (Vogue, Glamour, Working Mother, Child, etc.). First printing was 100,000 copies and Knopf quickly went back for an additional 75,000.
