I personally love the idea of a book trailer.It's just like a movie trailer, except you know, with a book you don't have video clips handy to smash together in a delicious gooey heap of anticipation. Which means you need your own footage to work with, and that can turn out pretty cool. Here are two examples of book trailers that I love:
Maggie Stiefvater is an artist and a musician as well as a writer, so she put together this stunning trailer for her tale of cold woods and werewolf love, Shiver.
Using a totally different approach, Libba Bray advertised her Printz-winning Going Bovine
by dressing up as a cow and taking a walk around Times Square.
Those are my favorites, anyway, but as book trailers get more and more popular, there are bound to be more fantastic ones. What are your favorites?
