A few of my favorites:
Get Known before the Book Deal [Use Your Personal Strengths to Grow an Author Platform], Christina Katz. I came by this wonderful resource through a friend who recommended it. Having a platform as an author has become very important in the publishing world. We have lots of competition out there and a changing industry. One of the things that will make a difference is if you have a platform. It takes you step-by-step through the process. Even if you already have published, Katz shares valuable advise and how-to information that will help you sell more books.
The Lineup: The World’s Greatest Crime Writers Tell the Inside Story of Their Greatest Detectives, edited by Otto Penzler. This book is such fun. You’ll get the inside scoop from the authors themselves. Whether you read or write mysteries, I think it’s a great addition to any writer’s library. Find out where these characters came from and how they developed. Read it one at a time or spend a long weekend curled up with the book. Prepare to be entertained.
