I’m in the board room at Simon & Schuster, my publisher. The walls are white. There is a l-o-n-g rectangular table surrounded by high-back chairs. My students are sitting in them. Each student has a cell phone on the table. But the students are looking at my editor, Jofie Ferrari-Adler. He’s at the head of the table with a bunch of bestsellers spread out before him – The Oregon Trail, Hothouse, Rin Tin Tin, Men in Green. He’s talking about what makes a great cover.
