I love book trailers! Short, sweet and to the point they give you a taste of the novel that you are checking out, except instead of just words they have music and special effects. I think they are very effective for getting your book noticed and an excellent marketing tool!
I'm a huge fan of Julie Kagawa's Iron Fey series. I devoured the first three novels (Iron King, Iron Daughter, & Iron Queen) within a week of me finding out about them, and now she's released the final book (The Iron Knight) that will wrap up the story arc for Megan and Ash! I can't wait to read it! If you haven't read this series, YOU MUST READ IT!
Not sure if it's for you? Then watch this book trailer for The Iron Knight and decide for yourself!
