Anticipation has been growing all year for one of the fall’s likeliest bestsellers, Colleen Hoover’s “It Starts With Us.”.

Arthur, 55, currently heads another venerable publisher, Little, Brown and Company, and will begin her new job on Feb. 11. She succeeds longtime Knopf publisher Sonny Mehta, who died in December at age 77 and had mentioned her in recent months as a worthy replacement. Like Mehta, Arthur has a long record of success. She will lead the Knopf, Schocken and Pantheon imprints and will report to Maya Mavjee, who has been named to the newly created position of president and publisher of Knopf Doubleday. Mavjee, who left Penguin Random House at the end of 2018 amid a corporate restructuring, will rejoin her old company on March 2.
