First of all, I love any writer who shares a first name with me. Betsy Lerner and I are also writers. Beyond that, I doubt there are many similarities.
In the second half of the book, publishing, Lerner gives terrific advice on seeking and landing an agent (she herself is one and knows of what she writes), handling rejection (even Stephen King garnered a stack of rejections before his first sale), knowing what editors are looking for, knowing what you as a writer wants, working on the book with your editor and marketing your work after publication.
I recommend this to anyone who is starting out as a writer. Lerner pulls no punches yet leaves you laughing at some of her lessons. They serves beginning authors well. Those of us who have published a book or books already can still learn from this book. It's a reference book full of common sense and oft overlooked advice on how to behave as a writer.
It should be on every writer's bookshelf -- after the writer has read it.
