Jane Green, 'Queen Of Chick Lit,' On Being A 'Lazy Friend' (VIDEO)

Jane Green, the so-called "queen of chick lit" was on Good Morning America this morning to talk about her new book, "Promises to Keep." Green explained that her most recent book is not autobiographical, but it is inspired by her friend who died of breast cancer, and deals with the relationships between women when cancer comes between them.

Green said that this experience with her friend taught her what friendship was really about, and made her realize that she had been a "lazy friend." "What friendship actually requires are acts of love," she said. "It's all about the doing and the showing." For Green, a lot of that doing was food-related. She cooked for her friend's family every day, and included many of her recipes in the book.
