Is there value in creating a book trailer? In promoting a novel months before it's released? I'm curious about this marketing tool which seems to be popping up everywhere. Working with a talented friend, I was able to create a wonderful video - a way to introduce my story, and have already experience over 20,000 views on YouTube. Wouldn't it be great if this translated into sales? I'm curious as to the results other authors have experienced by using this type of media.
