Wow. Just... wow. I never new "book trailers" existed, but I stumbled across this one - I think it was a link from Twitter - and I had one of those "why didn't authors think of this before?!" moments. I have never heard of the book, but now I so desperately want to read it.
When I actually finish my novel (this blog post is my procrastinaton), I will definitely be doing this - I know lots of artsy people who can help me out so it can't be too hard. I can imagine my own book trailer clear as day right now. An old man stands at the Wellington cenotaph wearing his medals on Anzac Day as the Last Post rings out, signalling dawn. He thinks back and what he sees is the crashing of the waves at the Red Rocks, a beautiful girl, a crazed young man, a young woman lying in a pool of blood, and a ship sailing away from the harbour with his young self on it, waving goodbye to his family and trying his best to forget about the woman who ripped out his heart.
