On my bedside table, I'm waiting to start this book, "Lessons in Chemistry." This extraordinary success begs the assumption: Bonnie Garmus is a seasoned pro novelist. Well, the first part is true. Bonnie has been a longtime successful copywriter. But the novelist part? That came way later. Fueled by a lifelong desire to write novels, she was 64 when Lessons in Chemistry, her first novel, was published last year—and this followed her receiving 98 rejections from literary agents.
