A portrait of the literary partnership between Pulitzer Prize-winning author Robert Caro (at work on volume 5 of The Years of Lyndon Johnson) and multi-hyphenate Robert Gottlieb, the quintessential New York editor (former editor-in-chief at Knopf and The New Yorker), who counts programming for The New York City Ballet and lucite handbag collecting among his hobbies. Caro’s granular dissection of how power is wielded in 20th century America is matched by the intuitive, meticulous approach of Gottlieb, with whom he’s worked for more than 50 years.
