So, the problem for me for this question is that most of the books I read and review don't actually have book trailers, that sort of thing being in the far future when they were published and marketed. And for the books I read that are recent enough to have book trailers, I just don't watch them. The truth is that I had never even heard of a book trailer until I started doing the 30 Days of Genre meme. So my range of choices is fairly limited, both by the nature of the books I read and my own personal lack of experience looking at book trailers.
read review) by A.S. King is a brilliant book about Saffron, a poor girl in modern day Pennsylvania, and Emer, an Irish pirate in the 16th century, and their oddly intertwined lives, as well as the curse that requires Emer to live out a hundred lives as a dog. I have no idea how the trailer for this book matches up to trailers for other books, but I loved this book, so I figure that's as good a reason as any to choose this as my favorite trailer. Because a trailer is supposed to promote a book, and anyone who picks up this book is going to enjoy reading it.
As long as I'm at it, I may as well point out that the other brilliant book by A.S. King that I have read is Please Ignore Vera Dietz (read review), and it also has a fun trailer to watch. I didn't select Vera Dietz here, but that is only because the book is not really a genre book, although it does have some genre-like elements. In any event, I'm going to put that book trailer here too, because I can. I hope that you enjoy both of the trailers.
