So no surprise I love book trailers. I even created a Pinterest board just for them (you can find that here).
But the most fun I've had so far has been making my own trailer for the third novel in my Tai Randolph/Trey Seaver series, Blood, Ash and Bone. If you're thinking about making your own book trailer, you can read my post on the subject at the Poisoned Pennings blog here (I include links to some of my favorite video-making sites).
And if you'd like to take a gander at the final product, then . . . here you go!
