When you are writing you must hook the reader from page one. This book focuses on fiction, but even with non-fiction when your prospective reader picks up the book they want to know why should I buy this book?
The thing that impressed me the most about this book is the fact that the author Les Edgerton has a great deal of experience on both sides of this subject. He is a well established author and he had also been an editor and knows what they are going to look for. He also asked questions from various agents and publishers.
